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.

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.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

Flight was delayed by over an hour and gate checked bags took 15 minutes to be delivered to the jet bridge.

We have taken this flight before and it is a tight connection and they were late out of denver and did not wait for us. The plane was there and the departure time had not passed but would not let us on. Next flight is very late and a connection through Newark - a big mess. Sooooo appreciate them holding the plane so we could catch the connection.

Upgrade planes to have larger overhead bins, especially on this popular route and first class. Easy flight to Chicago, good service in first class. Can't wait for seatback entertainment to be brought back. I like the free wifi and messaging with T-Mobile. Although, the tray tables are not big enough to work even on a small laptop - so why is it called "business" class?

The flight was delay roughly 90 minutes. Once we arrived at O'Hare, we sat on the tarmac for another 90 minutes. I understand that O'Hare is under construction however they need to figure out a solution as every incoming flight I have been on has been delayed coming to a gate.

We were stuck with no gate upon landing for 90 minutes. Unacceptable.

Horrible. Flight was delayed for 4 hours first till 7pm. Then for one more hour. Then again and around 9pm we were finally boarded and waited for catering delivery for another hour. At 10pm we were not interested on food at all. Tired, sleepy we arrived after midnight. Insane.

I've never seen such poor lack of information at a gate station in 69 years. The flight from COS was to depart at 12:37pm. At boarding time, the gate agent in the microphone mumbled something completely unintelligible. I understood one word. "mechanical". Nothing else. Absolutely nothing else was reported for the next 1-1/2 hours. Past the time for departure, at 12:37pm, the gate agent simply walked away and the station was left unattended, as all of the passengers waited expectantly. The board still said that the flight was ON TIME. That was hard to believe since it was then well past 12:37pm and we all were sitting at the gate and there was absolutely no gate agent anywhere in site. I stopped an employee who was standing somewhere else and said that we can use some information. Much later, the same gate agent said that he will have information for us about 5 minutes but he "doesn't know any more than you do." Of course, five minutes came and went and he did absolutely nothing. One and a half hours after 12:37pm, he opened the door and began boarding. No explanation, no apology. Once we were boarded, the same happened on the plane. We sat. No explanation, no apology, from any flight attendants. Finally, finally, a pilot apologized and explained that there would be a delay. WELL NO KIDDING !

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.

Full flight so overhead bin space ran out & bags had to be checked. When you’re in the last boarding group, you might as well expect that. Don’t pay to check bags though because when they run out of space for carry-ons, they check your bag to your destination for free. When traveling with children, no need to pay extra for seats, they will assign seats & have to sit your children with you.

It was great. It was just a commuter so I splurged on first class and it was wonderful. Wish all seats were this spacious. Enjoyed it and will do it again.

It was super hot. The flight attendant seemed forgetful and abrupt.

Deicing in Denver took forever and I almost missed my connection. De-ice faster! Not Americans fault.
