24 hours vs 1 day
Quick question - I'm flying to GCM tomorrow and have had an antigen test done this morning before work. This should be fine as Cayman Islands is a test the day before. However, Verifly is insistent that it must be 24 hours before, for which I'm just outside of. When BA come to check my paperwork, what will they use to decide who is right? Is there an authoritative source I can check?
