Scheduled to fly IAD-PWM on 7/15 (last flight of the evening). Landed thirty minutes late from RDU, and got EasyUpdate text/email/vm that flight to PWM had been canceled, and I was protected on the first flight out on 7/16. Called 1K Desk and got an excellent agent in HNL that confirmed I was all set for the morning, apologized that I would have to spend the night @ IAD, and sent me an email with the standard choices ($250 e-cert, 20%, 12K miles).. Took the $250.
