A Farewell Trip on the World’s Longest Flight

Zach Honig of Engadget flew Singapore Airlines Flight 21 for one of its last runs:

With just 100 seats on board, the all-business-class flight primarily serves deep-pocketed globetrotting executives — many work in the banking industry, often splitting their time between Singapore and New York. (Singapore Airlines retired a similar-length flight from Los Angeles last month.) The nonstop route saves travelers three hours or more over connecting options, including Singapore 25, which has a two-hour layover in Frankfurt. Those three hours, at least for the airline, weren’t enough to justify keeping the A345 in the air, due in no small part to the enormous expense of carrying the additional gas necessary to ferry passengers without a requisite refueling stop.
