Departing Thailand and going through Immigration at airport on day 91.

Should a 90 day report have been done, or not worry about it?

How can I cancel my ED visa? I am aware that leaving the country without doing anything doesn't mean that my ED is cancelled.

I had my last extension on my current ED and due date it's 27 january 2023. Decided to leave earlier to get out of Thailand.

I booked a morning flight around 650am somewhere in mid January. Messaged my language school and there was no reply... (Perhaps they missed it)

Now I was told that I have to leave the same day when my ED is cancelled, but my flight is in morning, couldn't go to immigration at chaengwatanna to cancel.

Can I cancel my ED at the airport directly? What documents do I need to prepare?

TIA
