Is this possible? Kind of urgent, I'm flying Saturday and completely forgot that they changed AirAsia flights to the old airport. I know you can do it at Suvarnabhumi but not sure about Don Muang??

Go to immigration today to get your permit. Better safe than sorry.

There is an office per below moderator post:

I can confirm that there is a re-entry office at Don Meuang.

Checked in for Air Asia flight, went through to Immigration (at least 14 counters open, no queues)

In the middle just beyond the immigration counters is a large office with glass windows, and a sign that says Overstays and Re-entry.

Just as an additional question - do you need a photo for the re-entry permit at the airport?

A photo is required for the form - at Suvarnabhumi they take as part of extra fee but have not seen any report on Don Muang.

lWhen I came in a few weeks sgo, I swear I saw some sign about re entry. That was on intake, not to obtain the permit.

My flight out is 7:15 am departure from Don Muang.

Does anyone know: Will the re-entry permit counter be open at - say 6:00 am - in time for me to get one before departing at this early hour?
