She tells the story on her website:
Did you guys know that Delta airlines won’t allow guitars to be carried on to their planes when you’re flying out of Tampa, Fl? Well, neither did I. I’ve flown in and out of this city many times, each time carrying my guitar as my carry on. Not today. They said it would have to go underneath. Which would be fine if I had known that before I brought only my soft case. So the only thing to do is buy the guitar a seat. Which I did. He’s flying under the name Guitar Womack and he’ll be strapped into the seat next to me. I wonder if he’ll get peanuts. P.S. I think I’ll upgrade him to first class. He’s been a good boy.
