Arriving in Maui was very easy. I looked at my watch as I was exiting the plane and again when I got to the ground floor to go to the tram that takes you to the rental cars. It took all of four minutes to walk to the gate, then up a slight incline to where the checkers are, show the QR code and then down the escalator.
The gate was close to the checkers. We were on American Airlines Premium Economy, just behind first class. First class was full, but the rest of the plane was 1/2 to 2/3 full. There were no other flights ahead of us.
I had uploaded everything needed (pictures, COVID test results, trip information) to the Safe Travels site and had the QR code at the Safe Travels site ready on our iPhones. The lady scanned them with an iPad, looked at our drivers license and gave us the pink sheet you need to pick up a car and check into your lodging, all in less than a minute. We did not have anybody in front of us, and there were perhaps a dozen stations to service everyone.
