Great advice already, just wanted to add, be sure to tuck an extra blankie in the bottom of his carrier and I always put a little pair of jammies or at least a shirt on Toto. We have flown with her regularly since she was about a year old and it's just "old hat" to her now. Some of the people at the airport in B'ham. have seen her so often, they get excited when they see us there!

When we leave the local airport here in Grand Junction for our "hop" over to Denver, we take an early flight and they
do not warm the plane before we board. It's really cold on the floor so I want to make sure she is warm. Also, if you are really lucky and get nice flight attendents, they might let you hold the carrier on your lap during the flight. We have been fortunate and had several wink and say "dog?? What dog??" I really appreciate those who do that and if anyone should ever complain, I would swear that we just sneaked her out and the attendent didn't know it!!

Most of them will at least let you take the carrier out long enough to check on him and give him a tiny sip of water. Also, it might be a good idea when you check on him, give him a little "pea sized" treat of Nutri-Cal.
Good luck and I hope you all have a wonderful vacation!!
