Can I leave Bangkok airport during a 10-hour layover while traveling from Singapore to Frankfurt?

@Sarah ****************

in that case I would check with the airline (TG?) to confirm. It sounds like you will be treated as a transit passenger and once you check-in in Singapore you will be checked all the way to Frankfurt - I think this means you will need to stay at BKK airport for the 10hr layover, and not be allowed to “cross the border” into Thailand (I’m just guessing here). If this is the case, I would do as others have suggested and buy a lounge access, or even a hotel room at the Novotel (a bit expensive though). Best of luck 😊

if you get 2 boarding passes, no problem.

They probably worried you get distracted and miss your connection flight. 10 hours may seem a lot but when you consider getting through immigration 2 times travel into and back from city plus checkin you only get a few hours in the city. I would book a hotel room airside and sleep and relax
