Deutsche Lufthansa AG will return five ageing Airbus SE A340 jets in order to boost the availability of first-class seats as travel demand continues to rebound from the coronavirus crisis. The widebodies will be brought out of storage and commence flying in time for next summer, according to the company.

The step means Lufthansa will remain the biggest operator of the A340 and the only major airline still flying the jet. Aside from the German company and its Swiss subsidiary, which has four in traffic, other operators are minor carriers like Iran’s Mahan Air and VIP airline Qatar Amiri Flight. Other airlines, from SAS AB to Virgin Atlantic Airways, have long consigned the once longest commercial airliner to the scrap heap.

The decision to bring back the A340s alongside five revived last summer follows a move to resume flights with some A380 superjumbos, the biggest planes in the Lufthansa fleet. The plans mark a shift in thinking on the high fuel-burn models, which at the height of the pandemic had seemed likely to be permanently retired.

Airbus delivered 377 units and ceased A340 production in 2011 after less than two decades. The aircraft struggled to compete with more fuel efficient twin-engine models like the A330 sibling from the same era, which had gained authorisation to fly increasingly long oceanic routes, something that had previously been the province of four-engined jets.
