Even tho I have my thai pass printed on check in as I did it all through royal escapes DMC, KLm Airlines would also like to see the insurance, hotel booking, taxi booking I tried telling them you have to have all that confirmed to even have the thai pass so annoying, so the royal escapees emailed me each booking upon checking the hotel dates were the wrong day what a hassle
TLDR : Answer Summary
Travelers must be prepared to show multiple documents including the Thai Pass, health insurance, hotel bookings, and taxi arrangements, as airlines thoroughly check all documentation to avoid penalties for any entry issues once in Thailand. Even if the Thai Pass implies approval, inconsistencies or mistakes can lead to added scrutiny and complications. Travelers are advised to carry printed copies of all required documents due to these strict checks by airlines.
