I decided to change my BKK-PVG flight to the redeye, which will cost me a good night's sleep but still give me "two days" in PVG. Seems like the best solution to my situation. Of course, if there's a schedule change, and it goes under 48 hours, I'll try to change it back. Buying another ticket would be clever, but wouldn't the Thai agents in BKK see my complete reservation and note that my "real" next flight is in 48 1/2 hours?
