Lufthansa flew its last passenger A340-600 on October 18, routing LH419 from Washington Dulles back to Frankfurt and closing out 23 years with the type. It was a quiet end for what was once the world's longest passenger jet — and it cut the map of remaining A340 flights down to a handful of airports.

Zurich is now the best place on earth to catch a ride. Two Lufthansa Group carriers base the four-engine jet there: SWISS, with three active A340-300s, and leisure carrier Edelweiss, with five. Edelweiss alone serves twelve destinations with the type in 2026, and some of its aircraft are loaned from SWISS, including the Zurich-Montreal route flown under wet-lease on SWISS's behalf. A bonus for spotters and riders: SWISS's daily Zurich-Dubai service returns on October 27, flown mainly on the A340-300 through the winter.

The clock is ticking, though. SWISS says its last A340s will be gone by early 2028, with Shanghai Pudong and Johannesburg already switching to the A350-900 in winter 2026/27. Edelweiss is replacing its five jets with six A350-900s and has already ferried the first A340 to storage in Teruel. Frankfurt offers a slightly longer runway: Lufthansa still has nearly a dozen A340-300s expected to fly until sometime in 2027. Many of these are among the oldest widebodies in regular European service, kept alive only because the Boeing 777Xs, A350s and 787s meant to replace them showed up late.

After that, the type effectively vanishes from anywhere easy to book. The only scheduled A340-600 services left are with Iran's Mahan Air from Tehran and Venezuela's Conviasa from Caracas — both operating under sanctions that make tickets hard to buy and new planes impossible to get, which is precisely why these old jets keep flying. Mahan is the collector's pick: it operates the -300 and -600, plus the rare short-bodied A340-200 on occasion, a variant almost nobody else has flown in years. One consolation for aviation fans: SWISS's final A340-300 will go on permanent display at the Swiss Museum of Transport in Lucerne by early 2028.

If flying a quad-engine long-hauler is on your list, the window is months, not years. Book a Zurich or Frankfurt departure this winter or in 2026, or grab the SWISS Dubai route while the A340 is rostered. Everything past 2027 lives in places most travellers can't easily reach.
