This appeal raises the question whether United Air Lines, Inc. (“United”) violated Section 703(a) (1) of Title VII of the Civil Rights Act of 1964 (42 U.S.C. § 2000e-2(a) (1)) by discriminating against plaintiff because of her sex.1
Prior to June 19, 1966, plaintiff was employed by United as a flight cabin attendant or stewardess. On that date, she was discharged for violating a company policy in effect at that time which required that stewardesses must be unmarried.2 United employed and continues to employ both male and female employees, including male flight cabin attendants or stewards on overseas flights. No policy or rule restricting employment to single males has ever been enforced. Nor have female employees other than stewardesses been subjected to any similar requirement.
In August 1966, plaintiff filed a charge with the Equal Employment Opportunity Commission alleging that her discharge constituted unlawful discrimination because of sex in violation of Section 703(a) (1) of the Civil Rights Act of 1964. Processing of this and similar charges against airlines was suspended by the Commission pending completion *1197of hearings on the request of several airlines, including United, for a written opinion that female sex was a bona fide occupational qualification within the meaning of Section 703(e) (1) of Title VII of the Act. 42 U.S.C: § 2000e-2 (e).3 After extended hearings, the Commission ruled on February 23, 1968, that female sex was not a bona fide qualification for the position of flight cabin attendant and reserved resolution of questions concerning the “no-marriage” rule for “individual Commission decisions in pending charges.” In August 1968, the Commission concluded that there was reasonable cause to believe that United had violated Section 703(a) (1) by discharging plaintiff. Two months thereafter, the Commission notified plaintiff of her right to sue her former employer in the district court, and this action was commenced a month later.
On cross-motions for summary judgment, the district court, 308 F.Supp. 959, found that plaintiff was discharged about June 19, 1966, because of her marriage. Although United then employed only unmarried stewardesses, it permitted its male stewards to be married. The court held that United’s discharge of plaintiff was an unlawful employment practice and granted her motion for summary judgment. The court concluded that she was entitled to reinstatement, including the restoration of her seniority and longevity rights. Jurisdiction was retained in order to determine her loss of earnings and whether the same relief should be accorded to similarly discharged United stewardesses.
Simultaneously, the court entered a decree enjoining United from discriminating against plaintiff because of her sex and ordering United to restore her to employment and to pay her compensation “for all pay lost from the time of her illegal discharge on June 19, 1966, to the date of her reinstatement.” David J. Shipman of the Chicago Bar was appointed master in chancery to make a recommendation for a money decree. Plaintiff was ordered to submit suggestions with respect to “the issue of whether the scope of the relief herein ordered should be made applicable to other stewardesses discharged by defendant.” Further proceedings below were stayed while an interlocutory appeal was perfected pursuant to Section 1292(b) of the Judicial Code. 28 U.S.C. § 1292(b). We affirm.
TJnited’s No-Marriage Rule for Stewardesses Discriminates on the Basis of Sex
United first disputes the finding of the district court that the no-marriage rule for stewardesses involves discrimination because of sex. Relying upon Cooper v. Delta Air Lines, 274 F.Supp. 781 (D.C.La.1967), United urges that the qualification merely distinguishes between classes of employees within the job category of stewardess in the same manner as educational or physical requirements.
In 1965 the Equal Employment Opportunity Commission considered the applicability of Section 703(a) (1) to discrimination against married women and determined that
“ * * * an employer’s rule which forbids or restricts the employment of married women and which is not ap*1198plicable to married men is a discrimination based on sex prohibited by Title VII of the Civil Rights Act. It does not seem to us relevant that the rule is not directed against all females, but only against married females, for so long as sex is a factor in the application of the rule, such application involves a discrimination based on sex.” 29 CFR § 1604.3(a).
This interpretation of the Act is “entitled to great deference.” Griggs v. Duke Power Co., 401 U.S. 424, 434, 91 S.Ct. 849, 28 L.Ed.2d 158. We adopt it as both reasonable and consistent with the legislative policies and history of Title VII.
The scope of Section 703(a) (1) is not confined to explicit discriminations based “solely” on sex.4 In forbidding employers to discriminate against.individuals because of their sex, Congress intended to strike at the entire spectrum of disparate treatment of men and women resulting from sex stereotypes. Section 703(a) (1) subjects to scrutiny and eliminates such irrational impediments to job opportunities and enjoyment which have plagued women in the past. The effect of the statute is not to be diluted because discrimination adversely affects only a portion of the protected class-. Discrimination is not to be tolerated under the guise of physical properties possessed by one sex (cf. Cheatwood v. South Central Bell Telephone and Telegraph Co., 303 F.Supp. 754, 759-760 (M.D.Ala.1969)) or through the unequal application of a seemingly neutral company policy. Cf. Phillips v. Martin Marietta Corp., 400 U.S. 542, 91 S.Ct. 496, 27 L.Ed.2d 613.
Viewing the class of United’s married employees, it is clear that United has contravened Section 703(a) (1) by applying one standard for men and one for women. Cf. Phillips v. Martin Marietta Corp., supra. Concededly, the marital status rule applicable to stewardesses has been applied to no male employee, whatever his position. More pointedly, no male flight personnel, including male flight cabin attendants or stewards, have been subject to that condition of hiring or continued employment.
It is irrelevant to this determination of discrimination that the no-marriage rule has been applied only to female employees falling into the single, narrowly drawn “occupational category” of stewardess. Disparity of treatment violative of Section 703(a) (1) may exist whether it is universal throughout the company or confined to a particular position. Nor is the fact of discrimination negated by United’s claim that the female employees occupy a unique position so that there is no distinction between members of opposite sexes within the job category. Considerations of the peculiar characteristics of the position only pertain to the claim of a bona fide occupational qualification under Section 703(e) (1). See 29 CFR § 1604.3(b); 5 cf. Phillips v. Martin Marietta Corp., supra.
The Marital Status Rule Is Not Justified as a Bona Fide Occupational Qualification
United’s second contention is that under Section 703(e) (1) (note 3 supra) the no-marriage rule reflects a bona fide occupational qualification for the position held by stewardesses. Its argument rests upon the acceptance of three propositions: first, the duties currently performed by stewardesses are uniquely dif*1199ferent from those assigned to other flight personnel; second, sex constitutes a valid criterion for filling the position of stewardess; and third, the no-marriage rule may therefore be interposed as an additional requirement for such employment.
We find it unnecessary to consider the validity of United’s claim that sex constitutes a bona fide occupational requirement for the job of airline stewardess. Even assuming that Section 703 (e) (1) might justify hiring only females for that position, that conclusion would-not automatically legitimate the no-marriage rule imposed exclusively upon stewardesses. A valid discrimination in favor of women generally in filling that occupational position need not warrant the imposition of an additional qualification which operates discriminatorily against those employees by comparison to United’s male employees. United’s no-marriage rule must stand upon its own feet. If, and only if, that requirement reflects an inherent quality reasonably necessary to satisfactory performance of the duties of stewardesses can the no-marriage rule be supported. See 29 CFR § 1604.3(b) (note 5 supra).
United has failed to offer any salient rationale in support of its marital status policy. The only reason specifically addressed to that rule is that United was led to impose the requirement after it received complaints from husbands about their wives’ working schedules and the irregularity of their working hours. This is clearly insufficient. Section 703(e) (1) specifically requires a correlation- between the condition of employment and satisfactory performance of the employees’ occupational duties. The complaints of spouses do not suffice as an indicator of employee competence. Moreover, by its very terms, the narrow exception in Section 703(e) (1) calls for employers to treat their employees as individuals. United’s blanket prophylactic rule prohibiting marriage unjustifiably punishes a large class of prospective, otherwise qualified and competent employees where an individualized response could adequately dispose of any real employment conflicts.
Similarly, the arguments advanced by United in support of its policy of hiring only females for this position fall short of establishing a basis under Section 703(e) (1) for its no-marriage rule. The marital status of a stewardess cannot be said to affect the individual woman’s ability to create the proper psychological climate of comfort, safety, and security for passengers. Nor does any passenger preference for single stewardesses provide a valid reason for invoking the rule. See 29 CFR § 1604.1 (a) (iii); 6 Diaz v. Pan American World Airways, Inc., 442 F.2d 385, 387 (5th Cir. 1971).
United has presented no direct, rational, or reasonably limited connection between marital status, job performance, and its no-marriage rule for stewardesses. United has failed to explain why marriage should affect female flight cabin attendants’ ability to meet the requirements of that position while at the same time leaving unimpaired the capabilities of male flight personnel, particularly stewards. Nothing in the job descriptions given by United offers a basis for that disparate treatment. Nothing in the institution of marriage necessarily compels the distinction. Accordingly, we hold that the district court properly granted summary judgment in favor of the plaintiff on this issue.
*1200 United’s Defense of Good Faith Reliance Upon the Written Interpretation and Opinion of the Equal Employment Opportunity Commission Is Inapplicable
United also asserts that its rule should not give rise to liability under Title VII of the Civil Rights Act since it “was in good faith, in conformity with, and in reliance on [a] written interpretation or opinion” of the Equal Employment Opportunity Commission within the meaning of Section 713(b) (1) of the Act.7
On July 1, 1965, the Commission published a regulation defining the phrase “written interpretation or opinion of the Commission” in Section 713(b) as having reference to
“[o]nly (a) a letter entitled ‘opinion letter’ and signed by the General Counsel on behalf of the Commission or (b) matter published and so designated in the Federal Register may be considered a ‘written interpretation or opinion of the Commission’ within the meaning of section 713 of Title VII.” 30 Fed.Reg. 8407; 29 CFR § 1601.30.
This agency interpretation of the operative statutory language reasonably confines reliance justified under Section 713(b) to considered official expressions of opinion taking two specifically defined forms. As Judge Wisdom observed in Local 189, United Papermakers v. United States, 416 F.2d 980, 997 (5th Cir. 1969), certiorari denied, 397 U.S. 919, 90 S.Ct. 926, 25 L.Ed.2d 108, “[a] broader reading might bind the Commission to informal or unapproved opinions volunteered by members of its staff.”
United does not contend that it relied upon anything published in the Federal Register by the Commission. Instead United relies upon a so-called “letter of opinion” of the Commission’s General Counsel as to the applicability to the airline industry of the Commission’s ruling on discrimination against married women.8 Nothing in United’s affidavit however, supports the claim that this document was in fact an “opinion letter” issued on proper request pursuant to applicable agency procedures. See 29 CFR §§ 1601.29, 1601.30. Significantly, the document referred to in United’s affidavit lacked the letterhead of the Commission and did not reveal the addressee. There is no indication that the General Counsel’s letter was “entitled ‘opinion letter’ ” or signed by the General Counsel on behalf of the Commission as required by the interpretive regulation. Moreover, the representations of the Commission itself, before this Court as amicus curiae, disclose that the purported “letter of opinion” was instead a September 22, 1965, internal agency memorandum from the General Counsel to the Director of Compliance with respect to the latter’s handling of inquiries he received.
Apart from the formal insufficiencies apparent from United’s affidavit, the content of the September 22, 1965, Commission memorandum itself also fails to support a claim of good faith reliance upon an official opinion letter. The memorandum merely states that definitive judgment on the legality of no-marriage rules must be suspended pending further determination by the Commission of possible Section 703(e) (1) exemptions. The only “opinion” expressed was *1201that the circumstances existing at that time prevented an unequivocal ruling that the guideline on discrimination against married women invalidated airlines’ no-marriage rules for stewardesses. The memorandum does not indicate a considered legal judgment approving the policy under the Act. Accordingly, we must conclude that the memorandum was not intended as the basis for employer reliance now claimed by United.
Intentional Violation Unnecessary
United seeks to escape responsibility on the ground that it was not intentionally violating Title VII. Such an argument has been rejected by the Fifth and Tenth Circuits, which have construed “intentionally” in Section 706 (g) as meaning the employment practice must be deliberate rather than accidental.9 Local No. 189, United Papermakers v. United States, 416 F.2d 980, 996 (5th Cir. 1969), certiorari denied 397 U.S. 919, 90 S.Ct. 926, 25 L.Ed.2d 108; Jones v. Lee May Motor Freight, Inc., 431 F.2d 245 (10th Cir. 1970). We agree with that construction of the Act. Cf. Griggs v. Duke Power Company, 401 U.S. 424, 432, 91 S.Ct. 849, 28 L.Ed.2d 158. The district court’s conclusion that defendant’s policy was “deliberate” was justified by the record and satisfies Section 706(g).
The District Court Had Jurisdiction to Provide Relief to Individuals Similarly Situated
As part of its decree, the district court retained jurisdiction to consider the possibility of extending relief to other stewardesses similarly discharged by United’s enforcement of its no-marriage rule. Accordingly, the court ordered plaintiff to submit amended or supplemental pleadings, or suggestions on that matter, and gave United leave to respond. United attacks this portion of the decree as inconsistent with the policy of Rule 23 of the Federal Rules of Civil Procedure. It urges that the “class” aspect of a Title VII action must be established prior to judgment on the merits. We need not anticipate and resolve the array of issues which may arise in the determination of the propriety of class relief. In its present posture, this case presents the bald question of the court’s power to grant such relief where justice requires such action. In our opinion, Rule 23 to the contrary notwithstanding, the district court possesses such power in Title VII cases.
The vindication of the public interest expressed by the Civil Rights Act constitutes an important facet of private litigation under Title VII. In Bowe v. Colgate-Palmolive Co., 416 F.2d 711, 719 (7th Cir. 1969), Judge Kerner recognized that such a suit is necessarily a class action “as the evil sought to be ended is discrimination on the basis of a class characteristic, i. e., race, sex, religion or national origin.” See also Jenkins v. United Gas Corporation, 400 F.2d 28, 33 (5th Cir. 1968). At stake, therefore, are the interests of the other members of that class, and the court has a special responsibility in the public interest to devise remedies which effectuate the policies of the Act as well as afford private relief to the individual employee instituting the complaint. Bowe v. Colgate-Palmolive Co., 416 F.2d at p. 715; Hutchings v. United States Industries, Inc., 428 F.2d 303, 311-312 (5th Cir. 1970); Parham v. Southwestern Bell Telephone Co., 433 F.2d 421, 428-429 (8th Cir. 1970).
*1202Section 706(g) of the Act (note 9 supra) grants to federal courts plenary powers to fashion affirmative relief eradicating present discrimination and redressing the adverse consequences of past unlawful conduct. Cf. Local 53 of International Ass’n of Heat & Frost I. G. A. Workers v. Vogler, 407 F.2d 1047, 1052-1053 (5th Cir. 1969). In Bowe, we held that this power “should be broadly read and applied so as to effectively terminate the practice and make its victims whole.” 416 F.2d at p. 721. In order to accomplish that result, we ordered that the “relief should be made available to all who were so damaged whether or not they filed charges and whether or not they joined in the suit.” Id.; cf. Griffin v. County School Board of Prince Edward County, 377 U.S. 218, 224, 84 S.Ct. 1226, 12 L.Ed.2d 256.
In affirming the district court’s power to consider extending relief beyond the named plaintiff, we express no opinion on the ultimate decision to be reached upon remand. Whether such relief is appropriate in this case must first be determined by the court below after consideration of the arguments advanced by the parties, including references to the safeguards of Rule 23. We merely hold today that the court may so proceed.
Injunctive Relief Was Permissible
Finally, United asserts that injunctive relief was improper because it had rescinded its no-marriage policy and had reinstated the plaintiff. However, when United rescinded its no-marriage policy in February 1968, previously terminated stewardesses were to be reinstated only on condition of their waiver of back pay, so that all effects of United’s discriminatory policy had not been erased. Indeed, United’s first offer to reinstatement to this plaintiff was also conditioned upon waiver of her back pay, and its final offer of reinstatement with back pay was not until January 3, 1969, after the filing of this complaint.10 In such circumstances, no abuse of the district court’s discretion has been demonstrated. Cypress v. Newport News General & Nonsectarian Hospital Ass’n., 375 F.2d 648, 658 (4th Cir. 1967); Bowe v. Colgate-Palmolive Co., 416 F.2d 711, 719-721 (7th Cir. 1969).
The decree below is affirmed, and the cause is remanded for further proceedings.
. Section 703(a) (1) provides in part:
“It shall be an unlawful employment practice for an employer—
“(1) to fail or refuse to hire or to discharge any individual, or otherwise to discriminate against any individual with respect to his compensation, terms, conditions, or privileges of employment, because of such individual’s race, color, religion, sex, or national origin; * * 42 U.S.O. § 2000e-2(a) (1).
. The no-marriage rule, requiring that female flight cabin attendants be single when first employed and remain unmarried under penalty of discharge, was first applied by United in the mid-1930’s. By letter of agreement effective November 7, 1968, United agreed with the Stewardesses and Flight Stewards of United, as represented by the Air Lines Pilot As- ' sociation, International, that
“marriage will not disqualify a Stewardess from continuing in the employ of the Company as a Stewardess, but any Stewardess who shall hereafter become pregnant shall have her services with the Company permanently severed as a Stewardess * *
The agreement does not abandon the single status requirement with respect to hiring. This Court expresses no opinion on the legality of that portion of the agreement which permanently severs any pregnant stewardess from United’s employment.
. Section 703(e) (1) provides in part:
“(e) Notwithstanding any other provision of this title, (1) it shall not be an unlawful employment practice for an employer to hire and employ employees, for an employment agency to classify, or refer for employment' any individual, for a labor organization to classify its membership or to classify or refer for employment any individual, or for an employer, labor organization, or joint labor-management committee controlling apprenticeship or other training or retraining programs to admit or employ any individual in any such program, on tlie basis of his religion, sex, or national origin in those certain instances where religion, sex, or national origin is a bona fide occupational qualification reasonably necessary to the normal operation of that particular business or enterprise, * * 42 U.S.C. § 2000e-2(e).
. Congress specifically rejected an amendment to the Act which would have so limited the force of the prohibition against sex discrimination. Such a limitation, it was felt, would emasculate the Act. See 110 Cong.Rec. 2728, 13,825.
. 29 CFR § 1604.3(b) provides:
“It may be that under certain circumstances, such a rule [against married females] could be justified witliin the meaning of Section 703(e) (1) of Title VII. We express no opinion on this question at this time except to point out that sex as a bona fide occupational qualification must be justified in terms of the peculiar requirements of the particular job and' not on the basis of a general principle such as the desirability of spreading work.”
. 29 CFR § 1604.1(a) (iii) provides:
“The Commission will find that the following situations do not warrant the application of the bona fide occupational qualification exception: * * *
“(iii) The refusal to hire an individual because of the preferences of co-workers. tlie employer, clients or customers except as covered specifically in subparagraph (2) of this paragraph [permitting sex to be a bona fide occupational qualification for the purpose of authenticity or genuineness, as in the case of an actor or actress].”
. Section 713(b) (1) provides in part:
“In any action or proceeding based on any alleged unlawful employment practice, no person shall be subject to any liability or punishment for or on account of (1) the commission by such person of an unlawful employment practice if he pleads and proves that the act or omission complained of was in good faith, in conformity with, and in reliance on any written interpretation or opinion of the Commission.” 42 U.S.C. § 2000e-12(b).
. No sworn or certified copy of this document was attached to United’s affidavit supporting its cross-motion for summary judgment, as required by Rule 56(e) of the Federal Rules of Civil Procedure. But since no objection was pressed below, we deem it waived. Noblett v. General Electric Credit Corp., 400 F.2d 442, 445 (10th Cir. 1968), certiorari denied, 393 U.S. 935, 89 S.Ct. 295, 21 L.Ed.2d 271; see generally 6 Moore’s Federal Practice ¶ 56.22[1], pp. 2814-2817 (1966).
. Section 706(g) provides in part:
“If the court finds that the respondent has intentionally engaged in or is intentionally engaging in an unlawful employment practice charged in the complaint, the court may enjoin the respondent from engaging in such .unlawful employment practice, and order such affirmative aetion as may be appropriate, which may include reinstatement or hiring of employees, with or without back pay (payable by the employer, employment agency, or labor organization, as the case may be, responsible for the unlawful employment practice).” 42 U.S.G. § 2000e-5(g).
. The record does not show whether United has offered other stewardesses unconditional reinstatement. The November 7, 1968, letter agreement between United and the Airline Pilots Association International, does not discuss back pay nor whether United may hire only unmarried stewardesses. See note 2 supra.
