Hi Mike: Interesting. When I went to Kauai last September with United, I too missed the midpoint by 4minutes. I had set a virtual poi at the calculated midpoint and then kept checking the distance to that point until we had to turn in the answers. With that distance times the speed given by the GPS and adding that time to destination to the clock time is how I came up with my answer.

The pilot gives passengers a variety of information so we can guess the time the flight crosses the midway point between the two airports. Should you have obtained permission to use your GPS on the flight, you might be able to have a little extra tool working in your favor. It is a bit tricky because the head winds change and the speed is slower during the first 20 minutes of flight as you reach the cruising altitude. I came within 4 minutes but someone else won the prize. I did drop a user POI close the the mid point to help future GPS travelers. Mike Michael G.
