One of my favorite museums I have ever been to. Just spent a solid couple hours there afterward picking the brains of former flight attendants for stories it seemed like they waited years for anyone to ask about. A delightful spot.
Also the TWA Museum at the downtown airport they fly out of is one of the best hidden gems of KC—we got a special tour at Airliners International in 2024 and they pack a lot of cool stuff into a small space. Ex-TWA flight attendants do the tours.
