I fully understand your point as we had it good for a year + and lucky, but the situation has completely reversed now and worryingly has got out of control with a government as pointless as Eunuch in a brothel
I have flown a lot domestically and internationally, including to and from Thailand on all available airlines, and I can say without any doubt that they all suck.
I can also say without any doubt that all of these airline ratings systems are about as unbiased as a mother and as rational as a rabid dog. They all get their 'support' from airlines and the travel industry.
The reality is that most people learn that there are only 3 real criterion when choosing an airline, and they are Price and Aeroplane and Pilots.
The problem is that in order to get the best price it means sacrificing one or both of the other two. Some people are happy to do that and go for price, price, price. But I would warn all that for the first year or so as the airlines return to full business, that number 2 and 3 are going to be far more important. If I am in a plane that has a problem, I would want to have the best pilots flying a modern and well maintained plane. On that basis Qantas is number 1 for best Pilots - period. Then it becomes which plane - what model and how old - and that varies from flight to flight. All of those top 10 are OK airlines, but they all have good and better planes and pilots. The best pilots in any company tend to fly the best planes - that is a good guide.
Yes well aware of that but I respond to your final sentence which was "Maybe you meet only europeans in the Isaan in the village or bars , I guess." So as I said your post up 'till that point was intelligent, you just lost some points for that unnecessary and irrelevant final sentence.
