So how do I plan for a late arrival into BKK due to delay on the part of the airline?

United just changed my flight (for the 17th time since Dec 2019) to now include an extra connection with a 45 min layover into LAX b4 I board my flight onto Narita/Tokyo!!

My initial plan is (1) contact ASQ hotel (2) contact insurance agent/company (3) edit details via CoE

What else should I plan for? And how am I supposed to come up with new paperwork when I’ll probably be camped out in a terminal corner somewhere. Some airports have crappy wifi and minimal outside mobile connections also!

Issues with fit2fly, RT-PCR test?
