Delayed over 3 hours, extremely rough landing on all four flights. Would not recommend

Delayed over 3 hours, extremely rough landing on all four flights. Would not recommend

The entire crew were wonderful but 1 flight attendant stood out with his sense of humor on the microphone. I told him as much as I exited the plane.

Maybe different snack selection. To much sodium in them. I know refrigerators are not available but there has to be healthier items.

Wasn't expecting this, but, we actually ended up getting assigned to the first row of seats!!!!! The extra legroom came in handy

Flight was delayed over 3 hours. Planes were dirty. Staff indifferent. And they serve vegan pretzels as snacks.

The flight was smooth. The Southwest experience has degraded overall, but this one was okay.

The checking experience in Orlando was terrible, almost missed the flight. Too many travelers and Southwest completely understaffed.

no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.

For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.

I think Southwest can offer a whole can of beverage instead of such a small cup

Requested an aisle seat at the gate and got it. The staff so friendly

Flight was very delayed so I was able to get on an earlier flight via stand-by. Crew communicated effectively around delay and worked to make customers comfortable. Wifi was ok, streaming TV was great. App functionality broke down once I was moved to stand-by on earlier flight.

Two of the flight attendants were cranky and seemed like they didn’t want to be there. Not up to normal Delta standards. And our bags didn’t make flight to Italy from Amsterdam resulting in having to make a trip back to airport which cost me 75 euros.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

I appreciate how quickly and kindly the people at the gate at DCA accommodated several of us who wanted to switch from the 6pm flight to the 5pm flight at the last minute. The flight crew was helpful to us too (dealing with luggage).

Waited on tarmac to take off for approximately 15-25 minutes. When landing, the taxi to our gate took a similar amount of time. This happened on both of my United flights.

Fine except from Chicago to moline three different gate changes and flight times

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

The first flight was delayed by an hour and a half, so we missed the second flight. They rebooked us on the later flight and I have to sit in the middle for more than 5 hours. Terrible experience. No more American Airlines.

Very good I can’t complain one bit. Thank you American Airlines for making my flight enjoyable and safe!

Flight was fine, but not having WiFi was a major negative

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

Would have thought that they would gas up plane before everyone got on board

The flights were terribly delayed and then cancelled which forced us booking another night at the hotel. Very poor management from American Airlines

American switched my flight to a 5 hour layover then cancelled my whole reservation with no notice and refused refund. Won’t fly with them again.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

The WiFi and app don’t work as easily as other airlines

Late. Then next flight was an hour late due to mx.
