Is there a limit to the number of times you can enter Thailand by flight?

I bloody hope not! 555

Only one at a time.

No, however, depending on your method of entry (visa exemption stamp) Foreigners who enter Thailand under this Tourist Visa Exemption category may only do so for 30 days at one time with a maximum of 3 times in a 6 month period by flight and 2 times a year for overland crossing.

No, why would there be. I suspect you've worded your question poorly.

No

Nope

One at a time, one at a time....

Just get a TR visa there like 1500thb then should not have any problems.

At the same time?

Yes, just one at a time my friend.

This also depends on where your passport is from? What do you look like? How are you dressed? Do you appear to have money? When they ask what you do for a living what is your answer? In case taken to a secondary room do you have 20,000 baht on you? A return flight?

If it looks like they have not showered in a week with holes in their shirt. They say they don’t have a job and just visiting for the 3rd time this year they may be denied entry.

Now if a well dressed person, well spoken, and nice clothes tries to enter Thailand for the 5th time this year they may not be questioned. Even if they are questioned what they do for a living and they say something like retired with a high pension that helps.

So it all just depends. Tell the truth as any lie will hurt.

As others have stated there is no limit to flights into Thailand, however after awhile immigration will see the stamps in your passport & and eventually say you are trying to live in Thailand on as a tourist

Some airports are worse than others, I have heard Don Muang is bad for picking on ppl with high entry rate on tourist status

Depends on your budget/finances/assets

It would more depend on how long someone stays each time ie if they stay the fulll 30 days + extension then flying out and back in is where the red flags start. For business travelers who fly in, stay a week and then fly out and are back again a couple weeks later repeatability there would be less scrutiny because they are not trying to live here on free entries.

No

Everything more than one at a time would be difficult if you ask me

2019 did 7 entries, nobody asked anything.

@Saty *****

no but each entry is at the discretion of the immigration officer

There is no official limit on Air Ins, but eventually you will get talked to by an overzealous I/O….

No
