A dummy ticket has a real PNR, booking code, or booking reference number and seems to be a standard airline ticket. If you utilise the "Manage my booking" option or the "My trips" section—both of which are accessible on many airline websites—you may verify them there. An itinerary or airline reservation are other terms for dummy-tickets.

Basically, a dummy ticket is a hold ticket that has not been issued yet. It comes with a live PNR that can be checked on the airline's website. It will be checked via Manage My Booking or Manage My Trip on the airline website. It is workable for visa submission, proof of return, and other temporary purposes.
Wow! You can get the dummy tickets within 10 minutes for just INR 350 or $5.
