Flight Crew Air Transport Pilot (ATP)
Communication Breakdown
Deviation - Track / Heading All Types; Deviation / Discrepancy - Procedural Clearance
Air Traffic Control Issued New Clearance; Flight Crew Became Reoriented
Human Factors
During climb; ATC asked where we were navigating to. The First Officer said GVE. We were told that wasn't on our route. ATC then cleared us to VXV and asked what our filed route was. The flight continued without any other inquiries from ATC. I then looked at the PDC and noticed a change from our filed route. The change was -FLUKY DCA246 PAUKI MOL- Whereas we were filed -GVE J42 MOL. I; the Captain; need to verify and cross check everything. Just because I'm on reduced rest doesn't excuse me of this important step. As a crew; we could have done a better job of communicating the changes to the PDC.
[Narrative 2 had no additional information]
EMB-145 flight crew deviated from cleared routing because they both missed a revised routing notice on PDC.
