Singapore Airlines has officially ended one of the longest flight routes in the world connecting Singapore Changi Airport (SIN) to Houston George Bush Intercontinental Airport (IAH) via Manchester Airport (MAN). This flight service, which spanned 18,544km each way, was the world’s longest one-stop passenger flight route. Here’s what we know about the decision to end the ultra-long Singapore Airlines to Houston route after 17 years in business:
Singapore Airlines Houston Route Ends
The now-discontinued Singapore Airlines to Houston in Texas route required between 23 and 26 hours of travel time each way. Normally, the first leg of the flight from Singapore to Manchester took around 13 hours, followed by a 2 hour and 24 minute layover, and an additionally 9 hours to Houston. In fact, the Singapore Airlines to Houston route’s had a layover in Moscow before shifting to Manchester in 2016 due to economic challenges in Russia.
The airline cited insufficient demand as the primary reason for discontinuing the route on April 1, 2025. According to reports, the service struggled with low seat occupancy rates, averaging just 64% over its history. Additionally, demand further declined in recent years with occupancy dropping to 33% in 2023. Other factors contributing to its cancellation include limited feeder traffic from Houston and evolving travel trends favouring shorter, more direct routes.
Although, Singapore Airlines will continue serving Manchester with five weekly flights to Changi Airport. Meanwhile, Singapore Airlines will use this freed-up capacity to enhance services to other European destinations. For those travelling between Houston, Manchester, or Singapore, it is now necessary to connect through major hubs like London.
