Unfortunate, indeed. Not a big fan of 737s, to be honest, but have taken TG service into USM a couple of times. I don't live in Thailand, not to mention Asia. Coming in from either India (where I have family) or US, flying TG is just much easier because of the connections where I have to take TG into BKK.
Hopefully, TG will be able to fly back to USM at some point - really enjoy vacationing in the area.
