my case I fly with is only 43.5” . Even my biggest case (Calton custom for an MD) is only 48″. Check your measurements. My 43.5 inch case fits in the overhead on 737s but my larger cases to not. When I flew the law was first come first served. If I had my guitar and did not want it checked I would pay for priority boarding giving me first chance at the overheads. If you are asked to move it say no. If it fits and you were there first it is your space to occupy. That was the law. Instruments had a carve-out which treats them differently than baggage.
