Hi everybody, apologies in advance if somebody has already asked this question but anyway here goes…I'm flying from Kathmandu to Suwannapumi and then I have a 190 minute break before flying on to Phnom Penh. I am fully vaccinated, and I can show this in a International Vaccination Certificate. Also, I have no luggage to check in. So, If I check in online with BKK Airways, can I just stay in transit for the 90 minutes (in between arriving from Kathmandu and leaving for Phnom Penh)? Is it necessary for me to go through immigration? (I don’t want to go thru immigration cos then I'm going to need a Thailand Travel Pass). Your suggestions would be gratefully received.
