I'm on a multi leg trip from Chicago to San Francisco to Los Angeles (and then back to Chicago). I'm using an older generation airport ninja case. The first two flights went without a hitch and I'm confident the flight home will also be uneventful.

I purchased mine used for $100, not realizing it was a slightly older model, but it is already totally worth the investment. I believe you can rent the case before you buy, which would be nice to make sure your bike fits. My 52cm wabi barely fit.
