"Until two weeks ago, Ellen Simonetti worked as a flight attendant for Delta Air Lines, doing her best to project the image of a stewardess from a bygone era. But it is Ms. Simonetti's very 21st-century activities that she says prompted Delta management to ground her, suspending her from flying in September and then firing her a month later.

"Ms. Simonetti has operated a Web log since January, calling it Diary of a Flight Attendant, and she says she did not hear from Delta about the site until after she posted a set of provocative photos of herself in her Delta uniform.

"But Ms. Simonetti said her supervisor called her on Oct. 29 and said she was being terminated for 'inappropriate photos in a Delta uniform.'"
