I've read and reread the Jet Blue bike policy.

JetBlue | Help Sporting equipment on JetBlue flights

I've talked on the phone and in person to JetBlue people. It appears that you cannot check a bike box over 80" (L+W+H). Not many bike boxes are under 80". Mine isn't. That would make flying on JetBlue with a cardboard bike box almost impossible.

Most other airlines have a 110" or 115" maximum.

Does anyone have experience with a larger bike box on JetBlue? They have the most convenient flights for me but I can't risk having them decline to take my bike.

Thanks for the help.
