OK, so I have a gig in Chicago next month that I will be flying to. If I can I would like to bring two basses. I have purchased a first class ticket on a relatively empty (Wednesday afternoon) flight as I suspect the airline will be more receptive to allowing a gig bag in the plane, possibly in the first class coat closet. That said there is always the risk that the flight fills up or for some reason they insist on a gate check. With that in mind are there any super durable gig bags that could withstand a gate check if one were to happen? Or are there flight-worthy double cases that I can just check at the ticketing desk? Any advice is appreciated. Thanks!
