Do I need a Thai pass for a 2-hour layover in Bangkok between Colombo and Phnom Penh?

Personally, I’d definitely travel with only hand luggage and try for my boarding pass airside. Given that you only have two hours I’d definitely avoid having to go through immigration.

The airlines will take no responsibility if your connecting flight is missed - as you have chosen this route.

That is even better. These third party websites are selling “illegal” connections in many markets. Even JAL and ANA genuine sites have been selling Haneda+Narita connections and international connections to domestic flight. Basically not allowed due to covid restrictions

, sealed route implies that you will not be entering Bangkok, and your luggage goes all the way to your final destination on its own. This means (most likely) not even going through immigration there. And I believe it also implies that you have your next boarding pass already. I don't specifically know the Thailand rules, but I know that in both Vancouver and Narita in November, we were escorted pretty much everywhere until we got to the departing gate area. Our luggage went to the final destination.

If you can change your flight route, I would look into that. But definitely try to keep to the same airline if you have checked luggage. That will help a lot.

What it does not say. You need a connecting ticket on a single itinerary. Getting Thailand pass for a two hour connection is not an option. ⬆️ . If the airline in Columbo even lets you board there is a chance you can get the staff of Lanmei airlines to collect your bags and passport from airside then issue you the boarding pass. Otherwise you would have to be sent back to Sri Lanka. About six months ago a woman from Burma was able to do this to get to UK.
