Never managed to check in online due to systems glitches. Was also unable to check in at the kiosk so had to rely on a patient PMUA employee to work her way through the new system to generate boarding asses. Seemed like they had a lot of people on the counters compared to normal. It appears I may have actually been checked in (or at least the system had captured all my check in data) but the system would not issue the boarding passes or tell me I was already checked in so I would not keep trying. On positive side the 777 with in setback EFI screen is great. Makes traveling in the back of the plane much better. Service was with a smile the whole way. Dulles lounge was SRO. Food was edible. Drink chits helped.
