Singapore 21: a farewell trip on the world's longest flight

As of tomorrow, the longest flight in the world will shuttle passengers on a 747-400 from Dallas, Texas to Sydney, Australia. That 15-hour, 25-minute hop on board Qantas 7 may not be the lengthiest in duration, but at 8,578 miles gate to gate, it'll lead the industry in miles flown. For a few more hours, however, Singapore Airlines' decade-long run from Newark, N.J., to Singapore remains the record holder for both time (more than 18 hours) and distance (9,534 miles).
