I am flying my dog down this week. Continental told me that if the layover was more than 3 hours, I would be charged an additional fee (I think they said $75) and they would take her out of the kennel and put her in a larger run for the layover. I ended up booking through American as it was cheaper and faster from he east coast. Larry, check with your vet in Oregon, this time I had to go to the USDA office to get my health certificate done. Anyways, the dogs handle the travel better than we do! smile
