Delta Air Lines has introduced an unexpected collectible for aviation enthusiasts—exclusive trading cards featuring different aircraft in Delta’s fleet. The unique trading card program, initiated by Delta employees nearly two decades ago, has become a cherished tradition among the airline’s pilots. The trading cards showcase a variety of aircraft corresponding to the specific type flown by each pilot.

A TikTok video posted by user sarowarrr went viral in November, capturing the moment a Delta pilot graciously handed two shiny gold trading cards to the delighted passenger. The video garnered over 18 million views, showcasing the popularity of these collectibles.

A Delta spokesperson shared insights into the trading card program, emphasizing that pilots are happy to distribute cards to customers who politely request them. The program was initially conceived as a means for Delta employees to share their passion for aviation. The current collection features 11 card types, each displaying a unique aircraft design. The designs, introduced in 2022, were created by Delta’s “Window Seat” visual design team, with input from flight operations employees and a voting process by pilots.

Collectors of the Delta Trading Cards appreciate the tradition, with enthusiasts often discussing the best time to request cards on platforms like Reddit. The consensus is that the ideal time is during the flight, ensuring a smooth boarding and deplaning process.

While the cards have gained popularity on social media, the spokesperson highlighted that the primary focus of both the crew and pilots is ensuring passenger safety and a smooth travel experience. Thus, not every pilot may have the cards, and the availability might vary. However, asking politely during the flight could grant passengers access to this exclusive and cherished collection of aviation memorabilia.
