Are you flying to Hawaii? Airlines love to play the Halfway to Hawaii game. For some the math can be complicated. Use this calculator to get you close to winning the prize! If you want to do your own calculation, there is a description on how to do it.
Good luck and we hope you win the Halfway to Hawaii game!
We are not saying that this will give you the perfect calculation, because so many factors can change such as wind and the speed that the pilot decides to go, but this will get you close enough to be in it.
