Trouble with calling and asking from what I've seen, is that people on the phone make up answers they THINK might be right, and regardless, you have no recourse when you get there if the counter person is of another belief... saying "So and So told me on such and such date" doesn't cut it... That happened to several people I know...
December 2011, I carried on a 3 piece T/D bow in a bow sock for 3 piece in my carry on... arrows were in a large PVC home-made tube in checked baggage...since then, no go! EVERY thing goes Checked baggage only!
Last trip I took, I shipped EVERYTHING via FedX to my destination...boots, bow, clothes, arrows, you name it...Better insurance and not much more expensive for the total weight then the danged baggage charges you do NOT know will be there when you arrive. Especially a concern if you're doing one of those 3-day or short hunts in the boonies where your gear might show up after you left!
