8.0 Very good
Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.
M
8.0 Very good
Offered to check carry on to final destination. This is the most absurd thing in the world. I'm carrying on because I need what is in the carry-on. I'm okay with picking up at next stop but then I will be on much larger plane that can accommodate it. Also, if there is ever a change to your flight. Go to the airport and have the people there fix your ticket. Don't do it over the phone or online with United they screwed us up and ended up with flights for our last leg that took off before our first leg.

4.0 Mediocre
The economy seats on the 777 was not as cramped as I had feared, but the food was terrible.
