KLM issued this statement:
KLM was able to operate flights on Sunday according to the original schedule for this Whitsun holiday weekend. Furthermore, by the end of the afternoon, more than 90% of the passengers who had been unable to fly to Amsterdam on Saturday evening had arrived at their destination, or been rebooked.
The number of passengers being rebooked is currently rising, which means that nearly all passengers have now been offered an alternative.
KLM expects its flights to operate on schedule on Whit Monday, June 6, 2022, as they did on Sunday.
KLM would like to stress that the decision to suspend passenger flights to or via Amsterdam on Saturday evening was extremely difficult and one that was not taken lightly. Unforeseen and acute circumstances beyond our control compelled us to intervene in this way. Unfavourable weather conditions combined with runway maintenance at Amsterdam Airport Schiphol led air traffic control to reduce capacity further on Saturday evening. Many aircraft were consequently unable to land in or depart from Amsterdam. This led to a build up of passengers at Schiphol, causing large queues to form. In the interests of guaranteeing safety at Schiphol and maintaining a manageable situation at the airport, it was not possible for KLM to bring passengers to Schiphol in a responsible manner.
