The SWISS Airbus A340 fleet is being retired after 23 years, with the first of four aircraft standing down on 14 October 2026. The move marks the end of four-engine, long-haul operations at the Swiss carrier.
What Is Happening to the SWISS Airbus A340 Fleet
Aviacionline reports that SWISS is beginning the definitive retirement of its four Airbus A340-300s. The first to go was HB-JMB, which operated its final flight from Zurich Airport (ZRH) to Enschede in the Netherlands on 14 October.
The three remaining aircraft, HB-IFA, HB-IFB and HB-IFC, are still flying as of the time of writing. According to Aviacionline, SWISS has not yet announced official retirement dates for these three aircraft, as their withdrawal depends on the delivery of new jets.
Where the Remaining A340-300s Still Fly
The three active A340-300s are operating routes to Chicago, Montreal, Johannesburg, Dubai, Mumbai, Shanghai and Málaga. These are some of SWISS's most demanding long-haul destinations, which explains why the carrier has kept the type in service while awaiting replacements.
The A340-300s were configured with First, Business, Premium Economy and Economy cabins. Power came from four CFM56-5C turbofan engines, the same generation of powerplant that the wider industry is now moving away from in favour of more efficient options.
The Wider Lufthansa Group Strategy
The retirement is part of a group-wide move. As Aviacionline notes, the Lufthansa Group is replacing its older four-engine jets with more fuel-efficient twin-engine aircraft, principally the Airbus A350 and the Boeing 787 Dreamliner.
Lufthansa itself is also in the middle of its own A340 wind-down. One Mile at a Time reports that the parent airline operated its final passenger flight with the Airbus A340-600 on 18 October 2026, with flight LH419 from Washington Dulles (IAD) to Frankfurt (FRA) marking the occasion. Lufthansa still operates a number of A340-300s, which are expected to retire at some point in 2027.
One Mile at a Time notes that Lufthansa had originally intended to retire its A340-600s at the start of the pandemic, but brought them back as demand recovered and delivery delays mounted. The A340-600 retirement was ultimately made possible by incoming Airbus A350-1000s joining the fleet.
What Replaces the A340s at SWISS
SWISS is standardising its long-haul fleet around twin-engine aircraft. The carrier currently operates 12 Boeing 777-300ERs and three Airbus A350-900s, with two more A350-900s pending. According to data from Cirium Fleets Analyzer, cited by Aviacionline, those two pending A350-900s were expected to arrive in November and December.
Alongside the fleet transition, SWISS is also modernising the cabins of its Airbus A330-300s and Boeing 777-300ERs. The broader fleet includes 25 Airbus A220-300s, 15 A320neos and seven A321neos among its short and medium-haul aircraft.
Why the A350 Is Taking Over
Aviacionline highlights that the aerodynamics of the A350 deliver better fuel efficiency and reduce both carbon emissions and the noise footprint compared with the A340. Running four engines instead of two carries a significant fuel penalty over long sectors, and that cost has become harder to justify as modern twins have grown more capable.

The Bottom Line
The retirement of the SWISS Airbus A340 fleet closes a 23-year chapter at the airline and reflects the direction of the whole Lufthansa Group. Four-engine widebody jets are disappearing from the European major carriers as deliveries of A350s and 787s gradually fill the gaps left by delays and pandemic-era groundings.
With three A340-300s still active and their retirement tied to incoming deliveries, the precise timeline remains open. What is clear is that the type's days at SWISS are numbered, and the A350-900 will carry the long-haul load going forward.
