KLM will cancel some flights from 26 October until early March because more aircraft than expected are out of service for maintenance or repairs.
The airline is also flying some routes with different aircraft than planned, and says the cancellations will leave more intercontinental planes available as reserves.
Over the weekend of 3 and 4 October, technical problems forced KLM to cancel at least five intercontinental routes at short notice, which frustrated passengers and disrupted crew schedules.
Maintenance and wider disruptions
A spokesperson blamed a mix of strikes, extreme weather and other natural events, and pointed out that KLM also keeps some aircraft in reserve to replace planes that are in maintenance.
KLM has not said how many flights will be cancelled.
Operational director Mathieu Essenberg, who started in the role recently, said the changes let customers know earlier what to expect and give the airline more flexibility on the day.
He expects the measures to make operations more stable as the autumn school holidays begin on Saturday 10 October.
The cancellations also cost KLM money at a time when it is working to improve its finances.
