KLM pilots have reached a preliminary agreement with the company about a better pay deal, averting the one-hour strike that was planned for later on Monday.

The two sides have a “headline deal”, KLM said on Sunday evening. The proposal will now be worked out in more detail and then put to the vote.

Union VNV had called for a 6% pay rise and improvements in working conditions, including more flexibility about work rosters for the airline’s 3,200 pilots. The company had offered no more than 5%.

No details of the agreement have yet been published.

Pilots had been due to strike between 11am and 12am, which would have led to 15 flights from Schiphol being delayed.
