Abstract
In an age where convenience, efficiency, and security reign supreme, air travel has adapted accordingly. One notable change: the elimination of cash payments on board for food, drinks, and other purchases. This shift away from bills and coins did not happen by accident, it reflected a deliberate focus on safety, security, and smoother operations.
