Pros: "The crew were polite and helped to assist the passengers who has the same seats."
Cons: "The entertainment on board was limited, shoddy, and frankly disappointing. Why you are asking customers to download the United app instead of providing onboard entertainment like almost every other airline in the world is unknown to me. In comparison with other airlines (particularly airlines in Asia), it was downright egregious. The airlines top people obviously have no interest in providing any comfort for the those who are unwilling to pay the extra money. I do not understand why the airlines believes people should have to pay for their own meal on a 7 hour flight when they've already shelled out the money for the flight. In addition, why should I have to pay an extra $89 for a so-called premium aisle seat? It's completely inexplicable that the state of all airlines in America have fallen to this level."

Pros: "The flight was very smooth and fast. Great crew!"
