Beware Tropic Air and traveling with a crate. They refused us boarding with the crate (there was plenty of room, we just got an ornery pilot) so we had to switch at the last minute to a boat, THAT was the trip from hell. And it didn't help when Continental smashed the original crate on the way down (thank goodness the dog wasn't in it) and couldn't find us a replacement. So much went wrong, on both ends, all due to to simple laziness and/or incompetence and a bad attitude though I think in the end I was more traumatized than the doggy. We did everything to fit the requirements but airlines, staff, check-in, customs, etc. were so disorganized. Maybe we just had bad travel luck. Others have had easier times....
