Flying on United to Hawaii? Typically you will get to play the halfway to Hawaii game. Download this app to calculate the time at the halfway point. You just put in the distance, time at takeoff, wind speed, airplane speed (numbers that the pilot gives you) and this app does the rest!
Even though you will have calculated the time at halfway, there is still some luck involved. The right answer is the actual time at the halfway point and that can be different from the calculated time due to things like the change in wind speed and the speed of the plane. Add or subtract some minutes and seconds and try to play as a team to increase your chances. Put the seconds on your entry because the winner is sometimes determined by seconds! Have fun, and while you are munching on your chocolate covered macadamia nuts you can thank Hawaii Outdoor Guides!
