Will my travel history impact my entry into Thailand as a Belgian expat in 2026?

You have nothing in that patern that should be an issue. Keep doing 2 months on 2 months off till they tell you to get a long term visa.

Je bent hier amper geweest. Ik kom ieder jaar keer voor 5 weken per visit. Geen enkel probleem bij immigratie. Zolang je geen extensies doet.

I would say you will potentially be pulled aside and questioned. Be sure you have a ticket out, accommodation booked and 20k baht or equivalent in another major currency in CASH

You will be fine. It is a new calendar year

A stupid question. Nobody really knows. No Thai IOs will answer you on FB.

TR visa would have been reassuring...

Geen verschil,dikke nek of niet

Looking at the full picture, your travel history goes back to early 2024, and immigration roughly assesses time spent in Thailand within a rolling 12 month period, not calendar years. Within the most recent 12 months before your planned entry on January 25, 2026, your total time in Thailand is roughly in the 110–120 day range, depending on exact exit dates, which is below the levels that normally trigger serious concern. Combined with the fact that your stays are spread out, you have clear time spent outside Thailand and Belgium as your home base, no overstays, no extensions, no border runs, and you are arriving by air with a confirmed return ticket, accommodation, and funds, this still fits a normal visitor pattern. You are approaching the upper end of routine tourist use, but there is nothing here that would realistically suggest de facto residence, so entry on visa exemption should normally be fine, with the usual caveat that questioning is always discretionary.

You should be fine

I dont think mentioning your flying business class had any relevance to your post . Are you showing off ?

If I was flying business class I’d be expected to be treated like royalty; if they don’t then you let them know!

Just get the TDAC

Thai Immigration will be impressed, on their knees, you are flying Business class.
