What a refreshing and informative thread - thanks everyone for the information and advice.

Does it matter if my cover letter has a generic salutation, or is there a particular individual to whom it should be addressed?

What's your advice about addressing the "other applications" question on the interview? I have several applications out and ultimately want a major job, but I don't want to make Frontier seem like a stepping stone. How have those of you with aspirations for the majors answered that question and gotten the offer?
