This rule usually specifies that passengers may be entitled to certain reimbursements, including a free room if the next flight is the day after the canceled one, a choice of reimbursement, rerouting, phone calls, and refreshments. When a flight is delayed, the FAA allocates slots for takeoffs and landings based on which flight is scheduled first.[2] The Transportation Department imposes a fine of up to $27,500 per passenger for planes left on the tarmac for more than three hours without taking off (four hours for international flights).[3] However, passengers are not entitled to direct monetary compensation under US law when a delay occurs. Instead, airlines are merely required to pay for lodging costs of passengers if the delay or a cancellation is through their own fault, but not if the cause is beyond their control, such as weather.[3]
