I spend an absolute fortune mainly with Thai airways as once upon a time they were a good airline !
Having been a gold member and reaching platinum membership I expected to be looked after as a valid loyal customer, I have 190.000 airmiles from this year and I have NEVER once had a free upgrade in 10 years of gold / platinum , the only privileges that I have earnt were through loyalty,
I’m very disillusioned with Thai airways and am now looking for an alternative airline that values their customers

any advise would be great
cheers
