I’ve actually flown with my guitar(s) several times. The first was when I bought one while in Mexico. I didn’t have a case for it, and so I slid it under the seat. Remarkably, it was still ok in the end. Since then, I’ve taken it in a case as a carry-on. Southwest is great about this. I’ve never checked it, though, except for the checking that happens at the gate. And I probably won’t ever check it after seeing this video. Enjoy!
And no, I did not make this. I just found it recently and thought it was really funny.
