This is really getting to be a strange travel day. My flight to NYC cancelled, so the gate agents sent everyone out of security to talk to the front desk. I ignored that and called the Gold desk. While I was arranging to take the 10 PM flight to Paris, and hop over to the nearby (shuttle bus) rail station for a train to NYC, they reinstated the flight - the only reason I knew about that was that the Gold agent told me, and then I verified with the desk. I've never seen that - I'm told it happens, but I've never seen it myself before now.
So now things are fairly good: we arrive late in NYC, but then it's ok, because we take the flight to Paris, only arriving about 4 hours later than we had originally planned. Lots of ugly waiting here at BWI, but better than dashing to the rail station, and then hoping that the cab could navigate from Penn Station to JFK in time...
