im quite confused why someone who would even consider this wouldnt spend more to get a direct flight?
you will pay $100 to avoid 15 minutes in line, but will put up with a 24-26 hour travel time?
im not 100% sure on the logistics from houston, may not be the easiest place, but would have to think you could fly to LA/NY and then to bangkok and have it be less then 24 hours total
