I hope they are wrong about that and you will be able to make that trip this year. I'm guessing they might mean regularly scheduled flights as before Covid rather than no flights at all. Whatever the airlines do, I would think it is going to depend on whether they are making money or losing money.
If that is the way it is going to be, and if Thailand wants high foreign tourist numbers again, but airlines that had always had service to Thailand won't provide that service, then they better talk to Thai Airways about scheduling flights to get people here and home - whether they are making money on those flights or not.
Then again, until 2023 or 2025, there might not be all that much going on in Pattaya for people to come to - assuming the bar scene even survives. I just wonder how many gay farang are going to plan expensive trips to Thailand, under Covid prevention rules, to go to the few go-go bars and the beer bars that are currently open.
I've been saying the same thing for years, and so far before Covid and also now, it's been falling on deaf ears. If the bars want to survive and get good customer numbers, they need to provide incentives to attract customers. At the moment, I am not impressed.
