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.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

It was literally one of the worst travel experiences ever. My flight got delayed by over an hour and there was no communication of this from the gate staff. I realized it by checking the screen periodically. Once on board the flight attendants continued to serve alcohol to a man who was clearly already drunk and that was making a bunch of commotion. Never again will I fly United!

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

Flight cancelled due to fog. No other flights available for 36 hours. Directed by United to book passage on another carrier, and submit receipts for reimbursement. Did that. United now states they will not reimburse. Currently out 2 grand.

- 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.

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!

The flight de-boarded after being informed of a 3 hour delay. The gate agent said we could go to lounge. The flight ended up boarding 20 minutes later and I missed it.

Seating was horrible. Small seats. Access to flight information and extras very iser unfriendly. Kept losing internet after paying for it. Staff in madison was as unprofessional and unhelpful.

We were told we had no flights before our flight was continually delayed then cancelled.
