We've flown our dogs ALOT.We move around quite a bit so both my RB girls were used to it.We havent flown with Kodie yet.Kiara would probably have to go down below,b/c she's mostly to big to go in the main Cabin.We have had good experience with flying our dogs.The people actually come on the plane to tell us that our pets are on the plane
And you have to pay for how big there cage is.Like our RB girls had a Medium and Large cage,and we had to pay.i dont remember how much though.Do you have a traveling cage??And remember to give them water,but you cant give them any food.

hopefully that helped some
