First time traveling to Thailand. We want to leave on Friday, November 20; returning Monday, November 30 or Tuesday, December 1. Would appreciate others' experiences with airlines, routes and layover times. Many of the cheaper flights have one and a half hour layovers in, for example, Tokyo. That doesn't sound like it would be enough time to make the connecting flight especially if take off is delayed even just a bit in new York. Thoughts and suggestions would be appreciated.
