I am a United frequent flyer and have been flying the airline for well over 60 years, and I can say it is one of the best (despite a couple of failings). It has the most destinations of any other airline. And the first American airline to fly back into Bangkok in years is huge. I understand that the flights will be daily from Hong Kong. I fly a lot i.e. more than 30 flights per year at a minimum and United has always treated me fairly and well.
