Just got back from my interview yesterday. Don't sweat it - the interview is 15 minutes tops and very basic. Know the airplane you're flying, relax and listen, and ask for the internship at the end. Smile, say please and thank you, etc. The interview starts when you get to the airport and ends when you deplane your flight home, so treat gate agents, FAs, etc. with the same respect you would Lisa Solitario, who will be interviewing you. Good luck, and let us know how it goes!
