Wouldn't touch thai air with a barge pole . Goverment owns most of the shares , they owe money to a few countries they cant even fly too as they will keep their plane , they were stuck in Germany the other week for 8 hours + because they couldn't pay for their fuel.
My thai wife is back in thailand , she can not leave the room AT ALL , only for covid test , then back to the room , cannot order anything from outside , 3 meals a day supplied by hotel .
Only thai embassy can arrange flights , my thai wife has just gone back to thailand , they had 50 seats on each flight for westerners to fly back also. Not cheap though .
I lived in the middle of no where before , these thai guys came round and connected to over head cables running down the side road by our house , all in a day , 1200 bath one off then paid about 700 baht a month unlimited, assuming some phone line , not sure how it worked , my neighbour's had it as well .
