Good, our flight was delayed but that was totally out of their control due to weather and a presidential visit.

The price. Omg $1100. Was crazy and it was not clear on the website.

Excellent. I had a medical emergency on flight SNA-ORD and the attendants were very helpful.

Usual wait for over a half hour for a gate at Ohare. They tell you you'll get there early then sit on the plane and wait almost an hour

Plane congestion resulted in a 1 hr wait from landing to arrival at the gate. This was in addition to also experiencing extreme delays on my incoming flight.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

The Wi-Fi did not work, so you weren't able to watch entertainment on your own device. They did not have wired headphones so you couldn't watch it on the in-seat entertainment screen either. There was plenty of time to do a drink and snag service but the flight attendants chose not to.

Standard flight with a drinks and a snack- overall very quick flight. The flight attendants were very strict, bordered on rude.

The aircrew was solid, the flight was chill, I had no issues. The gate agent was not the best. I was trying to use a military bag upgrade to move my bag from under the seat to the overhead bins and he told me there’s no overhead bins on the plane, argued with me why booking put a military member in basic economy (I don’t really understand this) and made it an issue to even try to help me stating I’d have to call reservations to get a bag upgrade. When every other agent with United can add it at the gate, this man couldn’t be bothered.
