A "dummy ticket" is another term for a reservation for a flight, which can be made for one or both of the seats and/or rates. Low-cost carriers (LCCs) and regular airlines are the two main categories of airlines. It is not possible to create a dummy ticket on a low-cost airline (LCC), but it is possible on other airlines.
