I so appreciate the crew members on each flight of United. They are outstanding.

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Unfortunately weather delayed our flight waiting for our plane to arrive and due to a little snow time was needed to deice the plane so departure was very delayed and I missed the connecting flight

Mean flight attendant. I wanted to reuse my plastic cup, but he (Matthew) said he can't for safety. I then said "I don't want water then" and he poured me a glass. I hope Matthew gets herpes and spends the rest of his life poor, lonely, and homeless.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

It was great. There were some issues prior to takeoff. The weather was poor so we had to go through deicing, and we were delayed a bit by the pilots' concern about one of the engines, but that's aviation. The pilots handled everything with aplomb, and kept us apprised

Reliable, nice crew, I fly often on that flight and I like it all.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The seats were comfortable and we had leg room. Great entertainment.

The flight crew where really good. Better then the crew from BNE to SFO

one crew said "he" didn't serve double alcohol drinks for travelers in exit rows. crew on prior flight did. Is this a AA rule, and the prior crew was being nice? Also, I think we deserve more than a 25% refund for losing first class seats when rescheduling a flight due to weather

I think we deserve more than 25% refund for losing first class seats when having to reschedule flight due to weather.

The flight was completely full. Crew was not happy. Everyone was rude and brusque. Travelling with an arm in a cast and seating in the first row of economy cabin (in front of the separation) I needed help retrieving my tray for the meal. A staff member literally threw the tray on my lap, without helping to take out the tray. Boarding was messy, with 300 people waiting in an encloses space with low ceiling. I will try to avoid AA next time I have a long flight.

It was a little concerning to hear the ground crew arguing with the flight crew over baggage space. Instead of taking them and checking them, they started checking for space in the first class cabin moving items around like the flight crew didn't know what they were doing. I was embarrassed for them.

2 hour delay due to equipment failure. No updates via the app and airport screens (which continued to show a departure time in the past). AA eventually switched planes and the new plane was not catered or cleaned correctly.

I booked an aisle seat and was given a middle. At 6'4" 230lbs, it is not ideal to fly in the middle row for myself and passengers.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.
