Guitar Do's & Dont's
Don't assume that every airline will let you play stupid at the gate.
1. Some airlines used to offer to stow your guitar in the hanging bag closet usually reserved for first class passengers, but with 9-11 restrictions, don't count on this nicety anymore.
2. Some airlines will let you check your guitar at the last minute, presumably putting your valuable instrument on TOP of the rest of the luggage and coming off first. But bagage can be loaded prior to take off long after you've taken your seat. So you could just as easily end up with a couple sets of golf clubs and a tool kit bouncing around on top of your guitar during the flight.
3. Some airlines flat out won't let you play these kinds of "I didn't know" games. And the end result could be either having to buy a seat for your guitar at a VERY high price, or being bumped off the flight for not having your luggage checked in time for departure.
If you're a touring artist that HAS to carry a pre-war flat top for your performances, then you'd better have a custom made, bullet proof, flight case for the guitar so that it can be checked as luggage. But you still run the risk of theft...
If you just want to keep your fingers limber while you're sitting in the hotel room between board meetings, then don't take a prized instrument along with you. Full sized guitars are bulky and unnecessary for this kind of playing. Instead consider the wide array of travel guitars (My personal fav is the baby taylor that comes with it's own hardshell case and fits in the overhead compartment of almost all planes). And if for some reason it does get damaged in transit, you're only out a couple hundred bucks vs. hundreds or thousands of dollars for a full sized professional grade instrument.
As always, YMMV...
