This was third leg of outbound trip. Boeing 777-200, flight was approx 75% full, so room to stretch out a bit. I had not flown United for about 10 years, first international flight with them.
Flight experienced about an hour delay in boarding due to "weather event" at IAD. Radar showed storms moving through to the south, but nothing was visible within 5 miles of the airport. Tarmac was never wetted down, so unsure of the reason for this at the busy evening rush time.
When loading started, it progressed at a fairly rapid pace. United appears to have changed loading based on seat assignment, which makes sense, ie: load window seat first, then middle, then aisle. We loaded fairly early, as were in the back of the plane. Changed seat assignment approx 3 days out to the paired seats that are in the rear of the B777 aircraft. Works nice for us as a couple.
Seats were typical economy. Legroom was normal, actually felt like I had more than the 737-8 that brought me to iAD.
Taxi and departure were non-events. Departed via Rwy 30, which allowed us to get altitude and swing out over the arriving traffic in the metroplex. We were over water in southern NJ. Due to the ground delay, sunset hit prior to hitting Long Island.
Dinner service was alright. Why do they keep insisting on serving that cold barley salad thing? very sour yet tasteless. Never saw anyone eat theirs around us. Drink service was very good.
Breakfast in the morning was yogurt and fruit, neither of which I like, so I ate the pretzels I saved from my earlier flights. Would be nice to have a pastry option or something else for us carnivores. No refills on coffee, which I really needed as I was going to have a full day.
The entertainment system worked flawlessly. Lots of choices for movies, TV, and music. Between the round-trip, I was able to watch a whole TV series.
Flew over London at sunrise, hit the continent and cloud cover until we started the descent into Munich. Landed less than 30 minutes late, so we made up some time.
On the overnight flight, rear of the plane was very quiet, not too many bathroom users and the crew kitchen area wasn't too noisy.
