The MD-11 makes its final scheduled passenger flight

Add the MD-11 to the list of aircraft no longer flying commercial airline flights.

Dutch carrier KLM had been the world's last airline still using the three-engine "tri-jet" for regular revenue service. But that came to an end Sunday morning with KLM Flight 672 from Montreal to Amsterdam, the carrier's final regularly scheduled flight to be operated on the MD-11.

Flight 672 -- flown by an MD-11 that KLM named "Audrey Hepburn" -- received a water-cannon salute when it arrived to Amsterdam's Schiphol Airport at around 6:35 a.m. local time (about 1:35 a.m. ET).

KLM acknowledged the significance of the flight in the statement, saying Flight 672 "not only marks the end of KLM's MD-11 operations worldwide, but also the end of a remarkable era in civil aviation."

Indeed, KLM's final regular flight MD-11 flight brings an end to the aircraft's nearly two-and-half-decade run of flying passengers for the world's airlines. The MD-11 first flew for a passenger airline on Dec. 20, 1990, debuting with Finnair on a flight from Helsinki to Las Palmas in the Canary Islands.

KLM plans to make three short – and already sold-out – "farewell" MD-11 flights over the Netherlands on Nov. 11, but those will not operate as part of the carrier's regular flight schedule. After that, the jet will exit KLM's fleet.

"KLM has in recent years invested in a modern, economical and sustainable fleet, in which there was no room for the MD-11," KLM says in a statement. "The aircraft, with its characteristic third engine in the tail, had become expensive to maintain and has relatively high fuel consumption. Spare parts are hard to come by and it is no longer feasible to maintain stocks."

More broadly, KLM's wind-down of MD-11 service also marks the end of "tri-jet" service worldwide following the February retirement of DC-10.

Biman Bangladesh Airlines had been the world's last passenger airline to use the three-engine widebody for regularly scheduled passenger flights. But the carrier operated its last inter-city DC-10 passenger flight on Feb. 20, flying the jet from its base in Dhaka, Bangladesh, to Birmingham, England, with a refueling stop in Kuwait City.
