Many airlines will let you do that at the counter. The trick will be is anything available. Maybe try calling the airlines and asking? Also when you check in see if they will let you change your economy seat to an unoccupied row. When I flew out here I did that and had a whole row to myself.....laid out and slept!
It seems every place (internationally vs locally) has different requirements. It's best to get from the source what is required. (For example to travel to Thailand I needed an Rt-PCR test but to return to the USA an Antigen is also acceptable.)
very true! One place didn't even put the type of test. I had to call the lab and request they put the type of test (PCR vs Antigen, etc)..they didn't understand why I needed that info!
I have taken several COVID tests (and had COVID), as well as had my family tested several times (and my daughter got COVID as well). All the test results I received had a draw date/time and a report date/time. When I checked with the airline they told me they look for report time since that is when you should be notified and get the results.
the problem with when the swabs were taken is many places take two or three days to return a RT-PCR (especially in the USA). That would leave little to no time to fly 20+ hours.
