What is the process for relocating a pet to Bangkok from the U.S. and what challenges could arise at the airport?

Peaceandrainfalls Korean was very strict about her staying within her carrier, but we did pull her carrier out from being wedged after takeoff. We first flew Denver to Seattle where we spent the night and gave her a big dinner. The day of the flight she was fed about of her morning meal but had some extra water mixed in. We then gave her a really long walk (3 miles) with lots of bathroom time. She was also able to pee right before we boarded at a pet relief area. She had a few ice cubes and a few freeze dried treats on board. Right upon pulling into the gate in Korea we ran to a bathroom stall where I had a pee pad and turf and she was able to relieve herself. I spent much of the layover on the stall floor letting her stretch her legs and giving her love. Unfortunately, Korea doesn’t have a pet relief area nor are dogs allowed out of their carrier in the terminal. However, it all worked out and we arrived in Phuket no worse for the wear. I will add that she has flown domestically almost 100 times, so she is a great flyer. I think the most stressful part of the journey was the USDA paperwork getting to us in time, and her ‘weigh in.’
