Just walking through the testing timeline For a San Antonio Maui trip, and realized how tight the window is. Can’t imagine being on the east coast or doing an overnight in California. Almost better to fly to CA and do test there over two days.
Sat Arrive Maui 2PM; 7PM San Antonio (+5 hrs)
Fri 7PM SAT -24 hrs
Thu 7PM SAT -48 hrs
Wed 7PM SAT -72 hrs
This suggests you’d most likely get tested Thu morning and need your results by Friday, or risk arriving Saturday, not knowing your results until you land, at best.
A 72 duration calculator across time zones is going to be real useful.
