On aircraft, oversize baggage fees will apply (but overweight fees usually do not). From experience, when paying for the bag ahead of time, fees are sometimes waived.

This bag has been used now many times when delivering new basses to our double bass shop in Miami. It has a few more scuffs but looks really good for enduring over a dozen flights without a problem.
