All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

Everything went smoothly and we even arrived a little bit early.

Great vacation. Can't wait till next year for another one.

Great flight but super high price. Glad it was a business trip and not personal

On time. Friendly staff. Took to long to pre bord all the specialty groups. Cramped small plane

The seats were comfortable, and the boarding process was pretty smooth.

3 hour delay. Had to change plans and was still delayed.

The staff was very friendly, professional, and courteous. The overall flight was a great experience.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Departure was delayed more than 1/2 hour while we waited for luggage (only) transfer from another flight/plane. Once approved for takeoff, the flight was excellent.

Delayed, toilets did not flush, pilot parked to far away from Gate

I like flying first class, and United has a nice one

It was great with United overall except for two things. 1) It was a 5-hour flight and we were with kids, so we were asking for extra snacks. They were extremely reticent to dole them out even though there wasn't any meal and the kids were starting to hit their limit towards the end. 2) Baggage didn't arrive until 80 minutes after we landed.

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight was canceled. I asked to be rerouted to OKC and then took an Uber.

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

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.

There were no TV screens - even in Business class. 5 delays, and only given $12 meal voucher! Terrible!

Concern Regarding Significant Gate Delay and Jet Bridge Issue Dear Customer Relations Team, I am writing to express my disappointment with the experience I had on my recent flight AA 2414 on Sunday January 18, 2026. What should have been a routine departure turned into a frustrating and avoidable delay due to an issue with the jet bridge at the gate. As a result, the flight was delayed by approximately 90 minutes while multiple gate changes were attempted. The lack of clear communication during this period made the situation even more challenging. Passengers were left uncertain about the cause of the delay, the expected timeline, and the next steps. This not only disrupted travel plans but also created unnecessary stress for everyone on board. I understand that operational issues can arise, but a malfunctioning jet bridge and the resulting extended delay suggest an area where procedures or equipment maintenance may need attention. I hope you will review this incident to prevent similar disruptions in the future. I would appreciate acknowledgment of this concern and consideration of appropriate compensation for the inconvenience and lost time caused by this delay. Thank you for taking the time to review my experience. I look forward to hearing from you. Sincerely, Dion Dillard

They made me pay $40 to check a bag that was listed as free when I bought my ticket. Then before boarding they offered to check any bags free.

The seat cushions were very worn so they were extremely uncomfortable.

Delayed, no updates, had a rewards number but was not working

AA should improve their in air internet & entertainment options. Seems unreasonable to charge $20/hr and should have some form of free connections. The entertainment options are also pretty limited, movies are outdated and the series only show 3-5 episodes.

The professionals have excellent customer service, the seats don´t have enough space.

It was cancelled at the last moment and the customer services seemed unnoticed to this change and hanged me off the phone the first time I called.

Staff especially Alan Hernandez was a great help with arrangements for my partner and me sit together. This made the trip do much more enjoyable. Thanks so much.

One of the flight was delayed an hour. We then boarded a new flight. We were told to unboard after some other time. To wait for the next flight for another hour. I paid for a short flight that turned in to half a day of travel.

No entertainment, charging, nor wifi on board but I napped for basically the entire time so it was alright. Was allowed to switch seats because the flight was not full but everyone was assigned to the back. Comfortable seats and we got moved to the emergency exit so the extra room was nice.

Painless trip. Only downside: No entertainment system (which we know with Viva & Volaris) and very small seat space. I'm petite and felt squizzed. I'm not sure how most overweight passengers do.

I was charge $90 for my bag more then the fight crazy!! And the plain hit a couple of birds on the take off bird strikes we returned back and had to change planes bad customer service everyone has an attitude problem!!! Bad experience!!!

The bad thing is they didnt send me the deatils about how much alowed bagage ehight 1 carryon or cheacking bag Also they just send in spanishlanfuage i couldnt understand emails

The boarding process was ridiculous. The boarded groups into a walkway just before the aerobridge (about 20 mins late), whilst we watch the crew stroll casually onto the plane, running late. And then they made us line up on then aerobridge with no aircon for 10 minutes before we boarded. Staff are just as ghetto as the customers. Wouldn’t fly again

They closed the gate over 25 minutes before departure and I didn’t get to board.

No empathy for my situation, arriving at the check-in counter 5 minutes after the deadline to deposit baggage due to a very delayed incoming intercontinental flight. The attendant simply stared past my shoulder and picked up the microphone to announce a "reminder that all passengers must arrive at least one hour before the flight" before speaking to the passenger behind me. I understand that there are rules above deadlines but at least show some damn empathy. It was Christmas morning and I'd been travelling for 20 hours for goodness sake!

3 seperate extremely rude unhelpful staff. Delayed flight. Lost my bag

Sat between 2 big men. I was uncomfortable. Flight was delayed twice. About 2 hours altogether.

It was a good experience. I do wish the seats were roomier. Also, I did not like being charged for my carry on bag

Exceptional take off and landing in snow and wind…thank you to the well skilled pilots!

I liked entertainment system being downloaded on my iPad. The selections were limited but I appreciated being able to use my own screen. The flight was just fine. My only issue was both terminals being far from the main airport. Especially stoning at LAX near midnight and having to wait for a bus to take us to baggage pickup. Very inconvenient.

Just fine but comfort is always an issue since the seats are so close

The Flight was fine, the staff treated me well, the flight got delayed over 5 1/2 hours for maintenance issues....but it worked out OK,, they were very apologetic about it, and it is better to not fly if there is any issue than endanger peoples lives, so in reality that was a good thing, It did cost me extra for parking because I went beyond the time I had purchased for parking at MSP. But all in all, Good flight

I did not take this flight because the reservation made by Kayak was wrong! Kayak owes me a trip from Minneapolis to Duluth.

When I got to the airport in Seattle, they told me the flight "did not exist". Kayak reserved me a seat on a flight that did not exist. This is inexcusable. I was able to change my reservation to a flight that actually did exist, but the flight was later and then I didn't make it in time for the next leg of my trip from Minneapolis to Duluth. Kayak owes me a trip from Minneapolis to Duluth, and a big apology for messing up my reservation.

The plane was freezing cold. Asked for a blanket and there were none. Was told twice that the pilots would warm the plane and it never happened Worst experience flying ever
