Before boarding the plane, you'd better relax your string as a whole or at least half a step. When the temperature drops and the air pressure increases on the plane, the strings will be stretched tighter, which will cause great pressure to act on the neck and the neck will break because it can't stand the sudden pressure.
In fact, this reason has been taken into account when designing the guitar, so if the strings are completely relaxed, it will also have bad consequences, and it is most appropriate to relax half to the first level. If you mail the guitar, you can do the same.
