Airline slots work a little differently than most slot machines. You don’t simply spin the reels to win. Instead, you use your airline miles to purchase “slots.” When you purchase a slot, you are given a certain amount of time in which to play it.
If you don’t play the slot within the allotted time, it will automatically be forfeited and you will not be able to win any money. Airlines usually have a set number of slots available for purchase, so it is important to purchase them as soon as possible. Airlines also have different rules about how many times you can play a slot before it is forfeited.
