If you have booked a SWISS flight in Europe in the past few years and found yourself on another airline's plane, that should happen less often next summer. SWISS says it will fly far more of its schedule with its own aircraft and crews from summer 2027.
In its October 27 announcement, SWISS said it will cut the number of aircraft it hires from other airlines, with crews included, from 26 to about 18. Its partnership with airBaltic ends after the 2026/27 winter schedule. Helvetic Airways becomes its main partner for this kind of flying.
What a wet lease means for you
When an airline wet-leases a plane, it rents the aircraft along with the pilots and cabin crew. The flight is sold under the SWISS name and flight number, but another airline operates it.
For travelers, that can mean a different seat, a different cabin layout and a crew that is not SWISS's own. The release does not detail what changes on board. Still, many frequent flyers prefer to fly the airline whose name is on the ticket.
Cutting wet leases by eight aircraft means more SWISS-branded flights will be operated by SWISS itself. The airline did not say which routes will switch back. When you book for next summer, the operating airline is usually shown before you pay, so it is worth a quick look.
Why SWISS needed help
SWISS says three problems forced it to rely on partners in recent years. The first was a shortage of Pratt & Whitney engines, which power its Airbus A220s and newer A320-family jets. The second was extra training requirements, and the third was too few pilots.
The airline says all three are easing. More engines are coming back, and cockpit staffing is improving. It will also fly more of its own Airbus A320s again.
CEO Jens Fehlinger said the change "is by no means a given," and that it required enough crews and careful planning.
airBaltic out, Helvetic in
airBaltic has flown for SWISS through the engine crisis. SWISS thanked the Latvian airline for its help but will not renew the deal once the 2026/27 winter timetable ends in late March.
Helvetic Airways, a Swiss carrier, has worked with SWISS for years and will now be its main wet-lease partner. SWISS says that gives it flexibility for peak seasons and short-term needs.
The release does not mention any change for Miles & More members. If the operating airline matters to you, check the "operated by" line on your booking.
Where to wait in Zurich and Geneva
Most of SWISS's European flights leave from Zurich's A and B gates or from Geneva. In Zurich, Business Class passengers and Star Alliance Gold members can use the SWISS Business Lounge (A) or the SWISS Senator Lounge (A), depending on their status. The SWISS Alpine Lounge (A) is another option in the same area.
See our Zurich airport guide and Geneva airport guide for every lounge and who can get in. For more on the airline and its fleet, see our SWISS airline page.
This is the latest of several SWISS schedule moves this month. It recently added Zurich–Toulouse and more flights to Paris, Nice, Tokyo and Montreal for summer 2027, and launched nonstops to Bengaluru.
