With airlines cancelling flights — most likely because of either the price or the availability of jet fuel — you might be tempted to cancel your flight as well.

You shouldn’t cancel.

Remember, if an airline cancels your flight, you’re entitled to a full and immediate refund back to your original form of purchase. However, if you cancel, then you only get a credit.

If you remain concerned about your future flight, then do something called trip stacking: keep your originally booked flight, then book a fully refundable ticket on a competing carrier on the same route as well as the same outbound and return dates.

If your original flight operates, then refund the other ticket. If your first flight cancels, get the refund and fly with a confirmed seat on the other ticket.
