As title states, SU1 and I were on DL9446 / KL652 on a KLM 789 IAD>AMS and just received the cancellation notice via text. No explanation. Was looking forward to flying J in their 789. Delta is working on an ATL>AMS flight in D1 for us so we can keep our AMS>NBO 1K / 4E hand-selected seats on a 744 (my first-ever 747 flight!).

Can't find any info on why the flight was cancelled -- weather, equipment, etc?
