Is there a priority lane for business class passengers at Suvarnabhumi Airport Immigration?

Fast track service does not mean to go through without immigration. Immigration checks the same as normal. But fast track is just fast to immigration.

I use fast tack due to my age. It's also for families with small children. I don't think your class of travel qualifies you, I may be wrong but good luck you will find out soon enough

They discontinued BIZ fast track years ago.

Can you pay at the moment you arrive for the fast track service? Cheers.

Business class is not that special

Don't forget to do your TDAC online

When u get to the big mass of people at immigration look to your left and walk 150 meters down to Exit 3. It is signposted Fast Track but most people don't go all the way down there. I flew in Bus Class on Emirates walked down to exiit 3 and walked thru fast track in 5 minutes there is hardly anyone there

Have you done your TDAC?

Priority is fast track ?

how do you access the fast track lane, where do you pay; online before you land?

If you are at the main passport entrance there is a lane marked Thai passports and this takes you to the fast-track area to the right of the main passport queues. There are independent fast-track entrances but they told me are not for business class. Make sure you retain your boarding card.

Fast track and priority lane are different things for BKK. Business class does not qualify to enter the separate Fast Track immigration area for arrival immigration. You instead go to the main immigration area but before you enter the immigration corridor, veer to the right and you'll see a small sign saying Priority Lane. There's normally someone standing there checking boarding passes to make sure you qualify. Make sure you say "Business class" to them. They are used to rejecting almost everyone and don't really bother checking, so if you don't proactively tell them "business class", they'll likely just wave you to the left side for general immigration instead of letting you in the priority lane.

There is fast track, it is on the right hand end of the immigration queues.

Yes. Just follow the fastrack signs. Biz class is eligible
