Flight delayed four separate times. I’m now one hour hours late to landing.

Definitely a southern flavor. Cordiality was evident even though no drinks or snacks were served.

No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

Overall Good! The weather delayed our takeoff from Atlanta and our arrival in Miami! If Mother Nature can mess up a flight she will do it every time!

N Everything was perfect from boarding to assistance to baggage in Tampa

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

The whole experience was excellent. As it most often is with Delta

We waited an hour on the runway to get a gate in Orlando

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

No screens or meal options. Freezing cold. Dirty seats. Left late.

Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.

It was perfect! I've never flown with United before, but I definitely will in the future

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

We sat on plane at gate delayed without communication as to why we were just sitting there

Agency very bad had to cancelled my booking too many changes in the flight changed my flight to 1 week

Flight was delayed by 6 hours... the level of incompetence was truly astounding. I won't be flying American Airlines again. I don't care if AA is direct and there is a layover with another airline, I'll take the layover.

Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

Little time between flight from Dallas to flight to Gainesville. We chose this one, 43 minutes between, because the price for a connection with at least an hour between, was so much higher. Had to ask passengers on the Dallas flight to please allow us to deplane ahead of them. The economy passengers allowed this. We had to walk very fast to the next gate, 35 gates away. Thankfully all in the same terminal. Getting to the small Gainesville plane was a little confusing as you enter an area that is boarding many small planes at the same time. We stood in the wrong line for about 15 seconds before realizing it was not our Gainesville flight. Since I had boarded at this gate in the past, I knew to check the signs carefully so we weren’t lost. The first class seat experience was wonderful. I really enjoyed the upgrade. We were offered an alcohol drink as soon as we sat down. I got something different but it was a great gesture especially since we really had to hurry to make the flight. We had packed expecting we might miss this connection, but made it. Our luggage didn’t miss the flight. American Airlines delivered our bags to our home the next day. That was very convenient!

The plane was large, not full, but one with 3 seats near each window and 4 in a row in the middle of the plane. There were screens on the backs of the seats for entertainment and information. To use the entertainment one needs ear plugs that physically plug into the screen. My husband had some he let me use as I only had blue tooth type. The stewards gave out some headphones to some, but when my neighbor asked for some, the steward said no. So maybe they ran out? Idk. Bring the old kind of headphones or earbuds if you want entertainment in case this is the type of entertainment offered. We had a very tight connection in Miami. 43 minutes. The other economy passengers allowed us to get ahead of them because I asked if we could since we were near boarding time for our next flight and 35 gates away. They were extremely kind. First class wasn’t going to allow us to pass through. We did make the next flight. Our baggage didn’t, but they were delivered to us the next day and we were prepared with essentials in our carry on packs.

B-class on an old plane with antiquated amenities and poor service. Landed in Rome w/o bag that didn’t make the connection (plenty of time in London). Bag will come to hotel NOT the day it lands but the following night!! Still waiting for bag…BA had nothing to offer in support and couldn’t even tell me their comp, told to submit receipts and then I’ll learn what is or isn’t covered.

Flight left on time. Captain provided relevant announcements. We had to wait 45 minutes to desembark due to the ramp closed because of lightening.

So overall the flight was just average and nothing special. They overbooked some of the flights and they ended up running out of overhead storage space so we had to check our carry-ons which wasn't terrible but we were inconvenienced because of the second connecting flight with a long layover we couldn't get our bags until the final destination. Most of the flight attendants were pretty good and overall the meals were not that great because the chicken was dry and overcooked. They also didn't provide butter or any kind of spread with the bread which is cheap and concerning. The American airlines staff at the check-in counter was kind of unprofessional because this lady just started singing in the middle of checking us in and that's weird. The worst part of the flights was the terrible conditions of the bathrooms which were unclean and did not have toilet paper or toilet tissue available which is kind of insane for a 14-hour and 8 and 1/2 hour flight.

Premium Economy Good crew, good service, excellent food. Seat back screen just not bright enough.
