You can buy cheap flights to almost anywhere in the world. But their low price comes with one major flaw. Those cheap flights are non-refundable. If you don’t make the flight, the airline keeps the money. In some cases, the airline will even resell your seat, making double the money at your expense. It is the same for concerts, cruises, rail travel, hotels, and more. This defect of non-refundable cheap flights and bookings is changing.
