Dummy-tickets
A dummy ticket seems to be a regular airline ticket and has an actual PNR, booking code, or booking reference number. You can confirm them there if you use the "Manage my booking" option or the "My trips" section, both of which are available on many airline websites. A fake ticket can also be referred to as an itinerary or airline reservation.
