A dummy ticket is essentially a hold ticket that hasn't been released yet. On the airline's website, you can view the live PNR that is included. The airline website's Manage My Booking or Manage My Trip features will be used to check it. It is feasible for short-term uses like submitting a visa application or providing proof of return.
Whoa! For just INR 350 or $5, you may have the dummy ticket in 10 minutes.
