Another big thumb's up for Heritage. Very nice people and very accommodating. Last year I flew cross country with my '53 Martin D-28. I have a Calton case for it, so I wasn't too worried about damage, but am always worried about the airlines flat out losing something. Heritage was willing to insure it for the plane ride for $50 each way. A little expensive, but worth it, IMHO, for my Martin. Of course, if they let me carry it on, I really didn't need to insure it for the trip. But I couldn't know if they would let me carry it on until I actually boarded the plane. I prearranged with Heritage to send them an email from the plane letting them know at literally the last minute whether or not I needed to insure it. As it turned out, I had to insure it one way and was allowed to carry it on the other way.
