Has any Traveler flown from The U.S. to Bangkok through Narita using the 1 April (Thai Embassy Wash DC) info for non-Thai nationals, a Fit to Fly certificate will be no longer required. However, a medical certificate with a laboratory result indicating that COVID-19 is not detected, using the RT-PCR method "ONLY." I am planning on traveling the 20th of April on American Airlines/Japan Airlines (MCO-ORD-NRT-BKK) using the RT-PCR test "ONLY." Appreciate any info from any traveler that has flown recently using this RT-PCR certificate only. I am reading some airlines are turning people back for not having the Fit to Fly certificate. Thank you in advance. Good Luck and Happy Travels.
