Thailand don't, some countries require a return flight 🛫 but not the airline, they will request because it's part of the entry requirements for them to take you to that country. Not Thailand even on a tourist visa it's not required. You may be booked on another airline so it's none of their business unless it's an entry requirement.
so have most foreigners living in Thailand, there not hard to get I just think some people a just don’t understand how to negotiate with “no have”. I don’t understand your first comment?
20th Jan 2020 was my first application so not an extension, this year be my my first extension? The extension is not due until the 27th April 2021, that is what is confusing me I had the 800,000 in my account until April and then I have kept it above the 400,000 with monthly income exceeding 65,000. I have a 90 day reporting on the 17th of Jan so I will go to Immigration to clarify then, expect I may get a fine if it has fallen below the requirements. I asked last visit but got a convoluted reply and did not have my partner with me to clarify but I will this time, and I will ask for list of requirements and documents they require in Udonthani Immigration as I understand they can change from office to office. Thanks again.
