What a terrible experience. 777 had had 10 seats per row (originally designed to have 9/row), but they added a seat per row. Felt like sardines given size of plane, tiny aisles, and high level of lights/air blowers. Flew with United Groups--they were incredibly inflexible and unhelpful as compared to Delta Groups. Terrible snack option for a 6 hour flight. Wifi didn't work even tho people paid for it. No mention of reimbursement. Even free entertainment didn't work. Horrible experience overall. Will not fly United again.
