Insights

Aviation History

The 747-400 is a key variant of the 'Queen of the Skies,' one of the world's most iconic wide-body jets, and was a mainstay of long-haul travel for decades.

Fleet Rarity

747-400s are now rare in passenger service; most are retired or converted to freighters. Thai was among the last Asian operators.

Record Flights

Famous for serving some of the world’s longest routes, including Bangkok-London and Bangkok-Frankfurt for Thai Airways.

Safety & Events

Thai Airways operated the final 747-400 commercial flights in its fleet in 2021, ending more than 30 years of 747 service.

Future Outlook

Mostly retired from global fleets, with some preserved and a few still flying as freighters or in special missions.
