Photoshop or any other image editor could be used, with a little extra work, to produce the fake airline tickets. They don't have a PNR code and can't be verified on the airline website. It is risky to use a fake plane ticket as proof of return or even to apply for a visa because fake tickets are easy to spot.

In order to pass immigration control or file for a visa, you have to buy a forged ticket with a verified PNR.

You may get a dummy ticket for just INR 200, or $3, in ten minutes.
