Called the UK number and got rerouted to a wonderful agent in Salt Lake City (less than 5 minute wait).
I'm booked on a new flight. It'll be a pain to get to the airport, and I'll be in Newark for 10 hours, but we'll make our original international flight.
They are canceling Sunday flights out of DCA for "weather" even though it was in the 50s today and all the snow melted and this weekend is supposed to be fine.
