Get online and find out where CARGO is....it is an office and buildings usually, on the other side of the runways or away from the terminal.....there will be an office there to check your ID and you might have to pay a $10 or $20 cargo fee....
Take spray bottle of water, paper towels for cleaning crate if needed - no chemical cleaners as pup is going back in it; fresh bedding (towels or blankie), leash with harness or collar (harnesses are tougher for the little ones to escape), a garbage bag or two for soiled bedding from the crate or pottying after he's out, water to give pup (no food or chewies! they might just come right back up and give pup negative vibes about car rides!...)
If you don't have a harness, stop in a pet store or walmart and pick up a cheapie nylon one....I always tell puppy buyers to have one as I have seen pups escape collars...you can usually get the pup out in the cargo office area and get it on him - then take him to potty! of course, he may potty there - but it is easy enough to clean up...
