Once you choose an airline....go to their website to find out their restrictions. This is the best source of info....
I do know that you can't have a container of liquid much bigger that 2 or 3 oz in your carry one. I'm sure anything larger will be fine in your checked bag.
I need to look into the thermacell issue myself.
My boss says AAA still has the flight plans and he is to get them tomorrow to see what flight we are taking. Should I put my binoculars and camera in my luggage, or take it in a carry-on? I will call whichever airline that we are flying with and see the restrictions.
