The latest delivery of 05/04/2024. Swiss adds Airbuses series 320neo to its fleet, usually 2 aircraft per year. New Airbuses often remain grounded due to problems with the Pratt & Whitney engines. Usually, 3-4 neos remain out of operation. Therefore, the retirement of 11 A 320-200s, taken over with one exception from Swissair, is being postponed.
