So I am STILL a bit confused about all this timing. We travel to SXM this Saturday. We changed our test appointments from Wednesday (72 hours) to yesterday (120 hours), got our negative results and the EHAS applications has been sent and approved, so we're good there.

However, now I read Spirit Airlines requirements for taking off from Chicago is to have a negative result 72 hours before the flight. What will they say when they see my test was 120 hours, not 72 hours prior to the flight?
