I don’t need to fly out or travel regularly to read the posts and comments on this forum and other visa related ones to know what I’m talking about and how often immigration ask about onward travel. For 300 hundred posts about someone saying they got stopped and asked by their airline for onward travel before being allowed to board there may be one from someone saying immigration asked them about onward travel plans. These are made up numbers. I don’t tally every post.
I have no idea what you are trying to say here. I’ve been here 35 years. I stated that the probability of being asked by immigration is very close to zero. The hardship if you are asked for an onward ticket and you don’t have one is the possibility of being denied entry. You almost certainly won’t be asked, but you could be.
How often I fly is completely irrelevant to anything in this conversation.
Depends on the office. Previously Phuket didn’t require a TM30 for short term extensions but now they do. I suspect other offices that didn’t require one may do so now.
The airlines probably have to factor in that although it’s a slim chance that extensions won’t be given it’s a possibility that they could be denied. I’ve seen it happen once (other than when an extension wasn’t allowed anyway).
