Just cancelled my SHA+ booking, they insisted that the requirement for the 72 hour covid testing was before arrival, not departure, and cited the Department of Disease Control for this requirement
"Copy of COVID-19 test certificate (the test date within 72 hours before arrival date) and mention method of analysis "
The DDC's website says right on it
"Get a COVID-19 RT_PCR test within 72 hours before departure with a negative result"
I dont know if they actually have a different policy, as some of them do, or are just confused and cant translate the difference between arrival and departure, just a heads up to anyone else booking to make sure everything makes sense
