Pros: Can't think of anything.
Cons: The seats were the most uncomfortable my husband and I have ever experienced. The huge headrest forced us to sit bent in a C shape with our heads bent down, no way to sit normally and relax. It was pretty close to torture for a long flight. I just wanted to rip the thing off the back of the seat. I will never fly on a B777 again if I can help it. Its particularly rich when the captain comes on the address system and tells us to sit back and ENJOY the flight. Additionally, boarding started a full hour before scheduled departure, then the flight was delayed an additional 45 minutes while they waited for somebody's luggage. If you boarded early, you got to enjoy sitting there nearly 10 hours for an 8 hour flight.
