Slots are used in the United States and around the world to limit the number of planned aircraft operations at extremely busy airports. This helps to reduce air traffic congestion, avoid repeated delays, and conserve fuel by keeping airplanes on the ground when they would otherwise be flying without permission to land or take off. However, slots can be misused to attempt to recoup losses from a previous round, which is known as chasing losses. To avoid this, players should always decide beforehand how much they are willing (and able) to spend on gambling, and only use disposable income for this purpose.
