Due to the reduced winter schedule there are some Cityflyer flights that spend long enough on the ground down route that it’s not possible to round-trip cater and so local catering is arranged.
Unfortunately the catering provider in AMS is unable to supply at the moment so you will get a tray with an ambient tapas or ploughman’s snack box, a packet of dried mango pieces and a Tony’s Chocolonely bar with crisps and Nature Valley bars available on request. The usual drinks will be available, ice may be limited but shouldn’t be a problem with the current temperatures!
