SWISS Confronts Growing A220 Engine Challenges in Geneva

SWISS is suspending flights from Geneva to Berlin, Hamburg and Pristina for the 2026-27 winter season starting October 25, as Pratt & Whitney engine shortages continue to ground parts of its Airbus A220 fleet. The cuts follow a summer schedule that already trimmed 12% of weekly departures across the network.

For Geneva passengers, this engine crisis has been quietly getting worse for three years.

A Fleet That Has Been Struggling Since 2022

SWISS was the launch customer for the A220 back in 2016 when it was still the Bombardier CS100, which makes this particularly painful. The airline has been leasing jets from airBaltic since as early as 2022 to plug gaps, and in 2023 as many as eight of its 30 A220s were simultaneously out of service awaiting engine replacements. The situation deteriorated further when a cabin crew member passed away in December 2024 following an incident where a jet's cabin filled with smoke. 

By October 2025, SWISS made a decision it had been circling for months, grounding all nine of its A220-100s for at least 18 months and cannibalising their Pratt & Whitney engines to keep the larger A220-300s flying. It is the aviation equivalent of stripping one car for parts to keep the rest of the fleet on the road.

Geneva Is Carrying Most of the Damage

The route cuts are not spread evenly across the network. SWISS has already cancelled a quarter of its short-haul destinations from Geneva in the summer 2026 schedule, with the airline's CFO openly describing the Geneva operation as loss-making and clearly behind market leader EasyJet. Winter 2026-27 takes it further — Berlin, Hamburg and Pristina are all being suspended from Geneva as the airline focuses its limited aircraft availability on more profitable Zurich-based flying.

The Geneva-Pristina route is particularly significant because of the large Kosovan diaspora community in Switzerland, for whom this is not a leisure convenience but a direct connection home. Those passengers will now need to connect through another hub, paying more and spending longer in transit. The Traveler

This Is Not Just a SWISS Problem

Across the global A220 fleet of 377 active aircraft, 64 are currently inactive, with SWISS among a long list of operators including Air Canada, Delta, JetBlue, Air France and Korean Air all managing the same engine shortage. Pratt & Whitney's GTF engine problems have become one of the most disruptive supply chain failures in commercial aviation this decade, and there is still no firm end date in sight. 

SWISS is managing this better than most by being surgical about where it absorbs the cuts. But for Geneva, surgical still means losing your direct flight to Berlin this winter.
