Desparately need your help….anyone?

I am scheduled to fly out (using Expedia) on NW63 from Amsterdam to Newark on the 20th November on a DC10, returning on flight 64 on the 23rd.

Expedia have just changed my itinerary saying I am now returning with KLM on flight 658 on a 767 (Major Booooo!) but my outbound flight hasn’t changed. Yet according to both KLM and NW’s website, flight 63 direct from AMS to EWR doesn’t exist on there.

Is flight NW63 from AMS to EWR still going ahead on the 20th November?

Can any of your wizards out there help me. The only reason I chose this flight over the others was so that I could get on a DC10.
