Aruba requires a negative Covid test upon arrival within 72 hours of final depature. You are able to test for a nominal fee at AUA upon arrival if you do not test prior to arrival or if your test does not come back in time. You will then wait at in quarantine at your hotel until a negative test comes back. It's usually a quick turn and is avaible in 4-6 hours. Aruba also requires that you purchase insurance through them in the event you are quarantined in Aruba. With the Aruban insurance policy you receive a "qualified to board" email to prove you are good to travel.

We had one of our covid tests arrive to our email late and the gate agent denied us boarding due to improper documentation even though we had our qualified to board statement from Aruba. The gate agent would not take into account our documentation. She would only go by the verbage on her computer.

On a side note: The negative test did arrive that morning but too late for us to fly.
