Swiss (LX, Zurich) expects to ground six aircraft during the summer, due to the ongoing Pratt & Whitney PW1000G engine issues, the company confirmed to ch-aviation. The grounded fleet will be A320-200Ns and A321-200NX, with no impact to the A220-100s and A220-300s in service, it added.

The company’s head of operations, Oliver Buchhofer, had said in a press conference that the number of aircraft grounded PW1000G engine issues could increase to up to 14 in 2024. Moreover, Swiss media outlet AeroTELEGRAPH reported that the airline is working under the assumption that the engine grounding issue will persist until 2026.

"We are currently examining whether we will have to temporarily withdraw a small number of aircraft from service again in the autumn," the company told ch-aviation in a statement.

Earlier this year, Swiss said it was engaged in “constructive” talks with Pratt & Whitney. No further announcement regarding compensation for the Zurich-based carrier has been made.

The ch-aviation fleets module shows Swiss currently has four A320-200Ns, and two A321-200NX inactive. The company operates an in-house fleet of 88 aircraft composed of nine A220-100s, twenty-one A220-300s, eleven A320-200s, seven A320-200Ns, three A321-100s, three A321-200s, four A321-200NX, fourteen A330-300s, four A340-300s,and twelve B777-300ERs.
