I've read many comments saying that they don't necessarily hone in on the exact timing of the test but, rather, the date that you test. If you test at 5 p.m. on Sunday for your arrival time on Wednesday, you should be fine (from what I've read - no personal knowledge.)
You should not have any problem. The day you got the test seems to be the determining factor when leaving the airport.
Did you travel already? If so, was your test timing a problem? I am also concerned about the timing!
We are scheduled to fly in on a Friday, so we are thinking testing should be done late on a tuesday? Ugh, can't believe they require 72 hours. Most places have changed to 5 days.
3 DAYS is accepted. So one could test any time on Tuesday for a Friday arrival. Or test on Sunday for a Wednesday arrival.
We arrived on Wednesday. The test timing was not an issue. Thanks for you advice everyone!!
