• Passengers on a LATAM flight were greeted in High Valyrian, a language from the "Game of Thrones" franchise.
  • The tie-up with HBO Max also allowed fliers to watch an episode of the prequel "House of the Dragon." 
  • Passengers who flew on three routes to Madrid were able to participate in the event, Simply Flying reported.

Crew members chatted to passengers on board three LATAM Airlines flights in High Valyrian, a made-up language featured in the "Game of Thrones" franchise.

The unusual conversation was the result of a collaboration between HBO Max and the airline, Simply Flying reported. The Chilean airline was hosting "Game of Thrones" fans on Tuesday to celebrate the release of the prequel "House of the Dragon," which premiered on August 21.

Those on board could watch the first episode while cruising at 30,000 feet, the airline said in a tweet.

Passengers who flew on three routes to Madrid were able to participate, Simply Flying reported. The airline said the routes were chosen because some of the series was shot in the countryside surrounding Madrid.

High Valyrian was first spoken by characters in a series of fantasy novels by George R. R. Martin, from which "Game of Thrones" was adapted. According to The Radio Times, High Valyrian was used in the Valyrian Freehold, a location in the series.

Fan interest in the language was so high that in 2019 online language learning site, Duolingo added the invented language so users could learn to speak it.

"House of the Dragon" was HBO's biggest premiere, drawing nearly 10 million viewers. Despite the original "Game of Thrones" series ending three years ago with a finale that divided fans, there was still significant interest in the show's new prequel. 

 The original run for "Games of Thrones" set viewership records for HBO and won four Emmys in the best drama category. More than 19 million people tuned in for the show's final in 2019, Insider reported
