In bid to attract more market share from all corners, airliners have been smart enough to offer scratch cards to their passengers. Most of the scratch cards have some gifts and offers printed on them once these are scratched.

These are ideally handed over to the travelers by the ticketing agents at the time of issuing the boarding pass.
Some of the typical offers and discounts include – 5% cash back on next flight with the service provider, discounts across popular accessory or shopping stores or discounts while in-flight on food items or snacks. One can gain endlessly from such smarter offer based scratch cards.
