Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

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.

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

Good crew. Boarding delays. Almost two hours wait for the bags in DC.

Safe made to destination. Late to start at GVA for icy reasons but we fought our next fly.

Great crew, excellent landing, good food. Over all great experience. Thank you!

The flight and staff was very good However: we could not check in using the website. We got the reminders and updated information but could not check in on either flight. And we did have the United App. Also just a tip for fellow travelers - going through customs in Chicago Ohare Airport it terrible.

My seat had a worn out cushion, which made it a bit uncomfortable. Other than that, the flight was excellent.

Take this flight regularly. Every single week same thing. Departure delayed. Make up some time in the air. Land at ORD and then wait for gate in "L" concourse Terminal 3 for 30-40 min-which yields a very delayed final arrival. Plus I get to taxi around and see every runway and drive over the bridge (IFKYK) over the expressway 2-4 times in most cases. Change the sched of incoming plane/work with FAA to improve traffic flow at ORD/change the timing of these flights. Whatever it takes. But do better.

- flight was delayed several hours due to weather (understandable) - flight delayed further and we were told by attendants "we are not sure where the pilots are but they are on their way" as we have to find different pilots for the flight - announcements over the PA were somewhat unprofessional by the attendants, seems they need more training and were not reading off the script. They showed their young age and immaturity in their communications with the passengers. They were not clear and lacked professional communication language. - going from a hub to hub we were also parked at the tarmac at ohare for an additional hour and kept being told "few more minutes". Please just let the passengers know the real wait time instead of hiding the truth. We understand there is traffic and weather delays, but we just want transparency. There are several logistics of our lives that revolve around what the attendants and pilots are sharing with us but they are not being transparant.

Boarding and Delays The boarding process for my American Airlines flight from Copenhagen to Philadelphia was a bit tricky. We experienced a gate change that required a long walk to a new area of the airport. Additionally, boarding was not via a jet bridge; we had to take a shuttle bus to the plane and then carry our luggage up the stairs ourselves. Furthermore, the bag drop didn't open until about 12:20 PM, which was only three hours before our scheduled departure. This meant I couldn't drop my bag off early and had to wait outside of security in order to drop off my bag and use the kiosk. The bag drop self-service kiosks also didn't open until about 12:00 PM when an American Airlines employee unlocked them so that we could print out our boarding passes and bag tags, which further created a backlog. The flight was delayed by over an hour because we had to wait for one of the tires on the plane to be changed. Flight Attendant Professionalism On a positive note, the flight attendant was very professional when handling a passenger who was sitting in the wrong seat. Even though the passenger was persistent and reluctant to move, the flight attendant calmly ensured the assigned passenger could take their seat. Kudos to the flight attendant for keeping his calm and composure, not allowing the issue to escalate, and handling it well under pressure while a line of passengers waited in the aisle to board. In-Flight Service The in-flight service was also fast, prompt, and efficient, although service had to be suspended for the last two hours of the flight due to weather and turbulence, which was outside of the crew's control. Limited Flight Options Please note that American Airlines only operates one flight per day in and out of Copenhagen. This means there are limited options available if your flight is delayed or canceled, which is something to take into consideration when booking.

This may have been the hottest cabin temperatures I have experienced on any flight prior to take off lasting for approximately 30 minutes. I am not typically one to complain but I was genuinely worried about the health of several passengers on the flight due to the extreme temperatures including a small toddler.

I will never but. through kayak again. and American Airlines. I will never fly again on. They're both thieves.

Nothing, I wont be flying American Airlines again and will not be recommending anyone to fly American Airlines. It was the worst experience flying I've ever had.

My luggage was not sent with us. Not sure if this is Envoy Air responsibility but that was a very BAD experience

The planes can use an actual cleaning. The armrest and seats do not appear to be cleaned on this one and most other planes.

Flight was delayed…once landed at ORD, no gates were available so made us wait for 56 minutes after we landed to let us out of the aircraft!

Very comfortable plane. The food was very good (for airplane food). The crew was great

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.

Perfect airline, super friendly, great service, tasty food. Would fly again.

Everything could have been better. What needed to be wrong with United went wrong

The flight was delayed. No information was provided as to the reason for the delay. There was only water offered during the flight.

Check in could have been a little cheerful rather than dour

Nearly every flight was delayed, I missed a connection at one point and the solution was unbearable. Added nearly 12 hours of travel time to my itinerary and was given no recompense.

Swiss air was a short flight to and from Frankfurt to Geneva. The crew was nice, and the service was fine. Would be nice if they had wifi available.

It was alright, you are sure about your bags even though they will be bag checked, you will get them back once you disembark.

Their service , specifically the way Lufthansa manages luggages is terrible
