KLM Grounds Seven 787 Aircraft and Cancels Flights Over Maintenance Issues
KLM Royal Dutch Airlines was forced to cancel five international flights during the first weekend of May 2025 after discovering improper maintenance procedures on seven of its Boeing 787 Dreamliners. The groundings began on May 3 at Amsterdam Schiphol Airport when KLM took the affected aircraft out of service, leaving more than 650 passengers stranded and disrupting travel plans across its long-haul network. The airline subsequently announced the removal of three scheduled flights on that day, and two further cancellations on May 4, as the carrier raced to bring its maintenance regime back into strict compliance.
On May 3, KLM canceled its services from Amsterdam to Mexico City, Chicago O’Hare and Portland after uncovering that certain maintenance tasks on key components of seven 787s had not followed prescribed guidelines. The flight to Mexico City carried approximately 250 passengers, who were delayed by a full day after alternatives could not be arranged until the following evening. Passengers bound for Chicago and Portland faced delays of three to five hours as KLM rebooked travelers onto other available services and chartered relief aircraft to operate on short notice.
The next day, KLM called off additional long-distance routes to Shanghai Pudong and Los Angeles, affecting roughly 200 passengers on each flight. Those travelers were swiftly offered seats on subsequent flights operated by KLM or partner airlines, with full refunds and hotel accommodations provided for those unable to accept alternative schedules. Ground handling teams and customer service agents were mobilized across Schiphol terminals to assist with rebooking and to provide real-time updates via the KLM app and automated messaging.
Despite the large-scale disruption, KLM made clear that there was no immediate safety risk to passengers or crew. A company spokesperson told local media that the seven aircraft remained grounded “while we complete accelerated maintenance in strict accordance with Boeing and regulatory guidelines.” The airline stressed that once the proper procedures are applied and documented, the 787s will return to service. In the meantime, KLM has deployed spare aircraft from its own fleet and drawn on codeshare partners to maintain connectivity on key routes.
This incident highlights the ripple effects of maintenance lapses in a highly regulated industry. Aviation regulators in the Netherlands and across Europe require airlines to adhere to rigorous maintenance standards, particularly on modern widebody jets like the Boeing 787, which feature advanced composite structures and sophisticated onboard systems. Any deviation from approved procedures can trigger mandatory inspections, grounding multiple aircraft until compliance is restored.
Passengers affected by the cancellations were reminded to confirm their rebookings via email or the KLM website and to arrive early for check-in on revised itineraries. Baggage delays are also possible, as ground crews work to clear backlogs created by the abrupt service changes. Travel advisors and corporate clients have urged all those with upcoming KLM flights to monitor the airline’s status updates closely and to factor in potential knock-on delays in their plans.
As KLM works through its accelerated maintenance schedule, the airline has pledged to review all Boeing 787 servicing to ensure full adherence to manufacturer and regulatory protocols. It will also engage with its maintenance contractors and engineering teams to reinforce training, oversight and quality control. With the seven affected Dreamliners expected to return to the air in staged phases over the coming days, KLM’s network should begin to stabilize by mid-week, allowing the carrier to resume its normal flight schedule and restore confidence among its global passenger base.
