If your flight gets cancelled, you should first contact the airline to let them know. Be sure to check for alternative flights or a partial refund. You can also try canceling your ticket and rebooking the flight at a different time. Consider asking the airline for a voucher, which can be used to reschedule for free or for a discount on a future flight. You may be eligible for compensation in the form of meal or hotel vouchers depending on the airline’s policy. Finally, check with your credit card company or travel insurance provider for further assistance.
