I have flown to Texas, Wyoming, Florida, Nebraska & Oregon on Turkey hunts in the past few years and had no problems as far as my double gun case holding up to the airlines abuse. Do yourself a favor and invest in a good quality double gun case, either aluminum or heavy plastic. The one I use is heavy duty plastic and I never had a problem with the case other than them loosing it on my return trip after the hunt, thank god they lost if for 4 days during my return trip from the hunt. Hopefully you are not going use the case just once and forget about it. Make sure the case that you buy has wheels to make it easier for yourself going from point A to B. I will be using mine again in less than 4 weeks to go to Florida on an Osceola Hunt. As for the Shotgun shells, keep them in a separate checked bag and in the original box that they came in and you should have no problems. Good Luck!!!
