Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

The Atlanta airport had thunderstorms, which caused our flight to be delayed by multiple hours. Once we were able to board.the gate agent was rude and was trying to rush us onto the plane because the team in the plane was about to run out of hours once we were all aboard the plane they ran into an issue where the catering truck was filling up the back of the plane and they left and had to come back because they didn’t fill it up all the way, causing even more of a delay. My seat was very tight. I didn’t have a lot of legroom overall this was a miserable experience.

Flight delayed due to ground hold. Republic airways did a great job.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Our flight was delayed multiple times and then canceled at almost 1 in the morning. We are a family of 7, traveling with 5 young children. When the flight we were supposed to fly on finally arrived after waiting all day after an international flight into JFK we were informed our flight was in need of a copilot and once they located one we would take off. Then our flight was cancelled because the copilot was over his hours and they couldn't locate another. They knew before taking off from the previous location that the copilot would be unable to fly. They could have communicated the cancellation of the flight hours in advance. Once they cancelled and the pilot and copilot got off the flight, they joked about it. While there are understandably limits on flight time for pilots, they can still handle the situation in a professional manner. The late cancellation resulted in angry passengers that required police intervention in the airport. It also occurred so late and included other delta flights that after trying 15 different hotels, we were unable to secure a hotel room, they were all booked. No rental cars were available in the area either. We ended up staying in the airport with the 5 children. We made it home after 54 hours of travel with maybe 2 hours of sleep. Our luggage was lost and had to be claimed at the airport at our final destination. This was the worst trip I have ever taken and the worst airport I have ever spent time in. I met two individuals in the airport that were kind and helpful; Tonya Maingot Williams from the can we hel desk that worked to help get us rebooked and home, as well as provide us with care bags for our extended stay in the airport. The other individual was Danielle from Buffalo Wild Wings that was so very kind when we found a place to take our family we were traveling with to eat, all 11 of us and we were able to sit down together to enjoy a meal during such a stressful time.

My flight home from Knoxville, TN, included a layover in Atlanta. I boarded the aircraft in Zone 5 and although there was limited overhead space, I was able to put my 'backpack' style roller-bag above my seat. Unfortunately, due to continued bad weather, we had to deplane. There were many people who would have missed their connection, so they rebooked. When we were re-boarding, the gate agent welcomed zone 5 and then made an announcement: All roller-bags for zone 5 passengers and higher will need to be gate checked. I promptly pushed the telescoping handle in and held my bag like a backpack. I was able to bring it on board, which was a relief. Upon entering the aircraft it became apparent that there was easily 40% open overhead space. There were audible signs of angry passengers who felt duped into checking their bags when in fact there were noticeably LESS passengers on the aircraft and TONS of overhead space. I'm not sure what kinds of parameters are used to determine when to cut off roller-bags from being brought on board, but it seemed deceptive and underhanded to have so many people get stuck checking their bags when clearly there was ample room for at least one more zone.

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Overall Delta was amazing from automatically booking us on the next flight once we missed our connection due to a delay to the constant communication throughout the entire process. We will continue to fly Delta going forward more and pay a little more if needed.

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

It was extremely hot in the cabin the entire flight, vent air was worn

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

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

The male air hostess was rude and didn’t provide good customer service. Didn’t even offer me a drink

This trip was a Christmas gift to our family. We were flying from Lexington to Palm Springs. When we were checking in the ticket agent said one bags was over weight by 4 LBS. We were flying first class which has baggage weight of 70 LBS per bag, one bag was 54LBS. We then had to take items from one bag to another. The agent also saw we had a dog with us. Once on the plane we were seated with the dog in the carrier. The United ticket agent came in the plane with two other people, I believe one was TSA and the other some security officer. The United agent said we had not paid for the dog ticket. We had paid for the ticket when we purchased our tickets. She did not give me time to find the email receipt. She then threatened all three of us with either I come with her or she would have all three of physically removed from the plane. I left the plane to pay for another ticket. She had to take my credit back to where we checked in. She acted as if it needed to be done immediately. She said we had 3 minutes. We then sat at the gate for approximately another 45 minutes. This was so embarrassing…to be threatened to be removed from a plane that we paid for all tickets including the dog. The flight attendance on the next leg of our trip were not very attentive to the passengers. On the plus side all the flights were on time. All in all, this was a miserable way to start a holiday vacation. United Airlines showed no compassion towards the whole incident. I feel we were purposely neglected.

Better perks for corporate employees whom travel often and spend a lot of money with the airlines. Snacks were terrible chips crackers are ideas. Flight and crew were great comfort was fine entertainment not so great so so called status members means nothing

Flight had mechanical issues and it was delayed 30 mins - some of us boarded and then had to deplane.

Delayed flight. Missed connection, AA put us on a later connecting flight. The connection flight was delayed 4 times and we had to deplane. Didnt get home until 3am, when I was supposed to be home at 8:30p. Zero compensation offered from American. I would not fly them again.

Better snacks but flight and crew were amazing on this flight

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

Bathroom ran out of TP and floor was wet. Crew seemed a bit unhappy, overnight flights may be harder.

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

Cabin was roomy enough to easily slide my carry on under the seat in front of me!

They needed to de-ice the plane. Apparently airlines have a problem keeping their de-icing vehicles in good repair. After we backed away from the gate we sat and didn't move for nearly an hour. Nearly an HOUR with minimal communication from the flight crew. Eventually the sun took care of what American Airlines could not and melted the minimal ice. We finally took of a hour late which, in turn, jacked up our connection in Chicago.

We were delayed in Charlotte for almost 2 hours because American Airlines didn't have flight attendants for our flight.
