Just an FYI boarded Boston to Doha last night for our BKK connection and QATAR Agent required a fit to fly, claiming it was only not required for Thai Nationals. We had decided to get it anyway. Be sure to print out the requirement page from your embassy....our first leg from Florida to Boston did not require it...😳
TLDR : Answer Summary
A recent traveler shared their experience with Qatar Airways regarding the requirement of a fit to fly certificate for flights from Boston to Bangkok via Doha. Although they were required to present the certificate by Qatar staff, other comments indicated that it is generally no longer necessary for travelers to Thailand except for Thai nationals. Additionally, several users recommended bringing a fit to fly certificate as a precaution. Overall, the consensus is mixed, with some citing that recent updates might have made the certificate unnecessary.
