KL is still operating AMS-ATL on April 1 with an A332. KL621 departs at 1020 and arrives 1340. There's still J and Y availability and you can buy a seat on the plane.

The issue is KL1610 (IST-AMS at 555a) has been cancelled. The other two KL flights that day are still operating but are showing wide open. Wonder if KL cancelled one because of flight bookings? Makes no sense to cancel the early morning flight as most of those pax are connecting to North/South America.

Edit: the flight from AMS-IST the night before on KL is also already cancelled. Maybe KL is short an aircraft for maintenance? (Note: the AMS-IST and IST-AMS flights that are cancelled for these days seem to be operating normally all other days.)
