Does anyone non-rev with cycling gear? I'm looking at the Thule Round Trip Transition hard side bike case, but it weighs 39 lbs empty. My bike is light, but not 11 lbs light to stay under the 50 lbs limit for luggage. If it all weighs in at over 50 lbs what happens? I've never non-rev'd or jumpseated with checked luggage. Do they charge non-revs to check a bag?
