I got this one last year for my trip to Illinois:

Has room for everything + spare socks, shirts and whatnot stuffed in there to save space in your other bag. (airlines only allow two checked bags now, 1 bag + 1 bow).

Sturdy as heck for a plastic case, but a little heavy.

ONe problem though, I don't know if my new XT fits in it. I bought it mainly because my old Fireflight was 39" ata and most cases barel y fit that.
