If you could ask Richard Branson any question, what would it be?  Let me know because I'll be on a Virgin America flight with him the week after next, and I plan to ask him your most ingenious and provocative questions ... and videotape the answers to share with you all here.

I'm flying with Sir Richard from San Francisco to Toronto--on one of Virgin America's first international flights--to interview him for Conde Nast Traveler.  Our readers have voted Virgin America their favorite U.S. airline for the past two years--here's why--and now that the carrier is going international and growing its fleet by two-thirds by the end of 2011, you can imagine I've got a slew of questions for him.

But right now it's your questions I want to hear. Please post them on my Truth.Travel blog, PerrinPost.Truth.Travel, by Friday, June 25, at 9:00 a.m. Eastern Time. The person who asks the single best question will win two roundtrip tickets on Virgin America anywhere the airline flies. As for the runners-up, they'll get videotaped answers from Richard, posted here.

Only one question per person is allowed, and you've got a 50-word limit. You can check out the other contest rules here. 

Can't wait to hear your clever questions!
