A flight attendant of Delta Air Lines has sued the company and JetBlue Airways for failing to take action on an employee who prevented her from working because her dress was not provocative.

In the lawsuit filed with the Pittsburgh federal court on Friday, Karin Keegan, 37, of Upper St. Clair in Pennsylvania said she reported to the two airlines' management that Oliver Angus of JetBlue prevented her from boarding a JetBlue plane that will ferry her to her job assignment in October 2007 because her clothes was not provocatively enough.

"He wanted her to change to a lower-cut shirt and tighter pants, and wear more makeup before letting her on the plane," Keegan's attorney, Samuel Cordes, said Monday, according to the Associate Press.

Keegan said Angus allowed other flight attendants to board the plane and denied her entry again after she changed into a more provocative outfit because she was already late to board the aircraft.

Keegan has stopped boarding JetBlue planes to avoid harassment from its male workers.

Delta has yet to issue a statement about the suit while JetBlue refuses to comment on matters it says is under litigation.
