Flying with a guitar that you care about can be a nerve-racking experience. Normal guitar cases don’t offer enough protection and the professional’s standard Calton cases are $600+ and heavy enough to make your arms lengthen.
Here’s a case designed for flying that is light, well designed and pretty much indestructible. It costs around $160-$200 and you can put your instrument in it by itself, in a soft and light gig bag or in your normal hard shell case. I like to put the guitar in a gig bag to use for light weight protection when I get to my destination.
The case also comes with well designed wheels that you attach with velcro and are stored in the case when not in use.
