That's the letter.
One other thing which I forgot. Back when I was flying a lot, the absolute BEST time to fly with a guitar was on a Saturday afternoon. The flights are usually almost completely empty, so you can frequently get a whole row in the back of the plane to yourself, which makes it much easier to bring on your instrument. Flying on Saturdays, I used to be able, as often as not, to get not just one row to myself, but have two or three rows free. Absolutly the way to go, if you can get it.
