What should I do about flight booking while waiting for my Thailand visa application?

Book on an airline that gives unlimited rebooking. Very easy to initially book to stay within entry requirements for the airlines etc.

i wonder if the airlines are aware of the new rules eg you can stay for 45 days + another 30 days before you need a flight out of the country.

IF you are wanting to stay longer... land borders are OPEN (All except Myanmar which is CLOSED to foreigners).

You could enter Thailand Visa exempt...giving you a 45 day stamp plus one 30 day extension of stay from your local Thai immigration office for 1900 Thai baht = 75 days

Enter flight details for the day that you are planning to go. Your flight details won’t be mentioned on the visa.

Any reason you waited SOOO long before you applied for the eVisa online?

I would say unless you get EVERYTHING correct the first go, it's unlikely that you'll get approved before you fly if indeed you fly next week 😕

I mean even if you applied and it wasn't approved before you flew in you could still enter on a the visa exempt entry plan and get 45 days and then IF that tourist visa was approved you could exit/re-enter the country to stamp in on it

Unfortunately that you want to stay here for as long as possible doesn't mean you qualify for any other visa option. 😮

and yes, you have to upload flight information to apply for the visa, SO book a flight.

OR

You could come in without any visa at all and you would get stamped in on a free entry stamp for 45 days and you could extend that one time for 30 days at the immigration office where you stay for 1900baht. That gives you 75 days in country to sort out another option to stay longer

You can extend the tourist visa one time for 30 additional days.
