We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

My flight from Atlanta to Oklahoma City was delayed multiple times. I ended up arriving in Oklahoma City nearly two hours later at around 1:50 am the following morning. This was a highly disappointing experience.

My Delta flight 2423 from Atlanta to Oklahoma City got delayed multiple times. It was originally scheduled to depart at 10:41 pm EST with a 11:58 pm CST arrival in Oklahoma City. However, after multiple delays, the flight finally departed Atlanta at around 12:40 am and arrived in Oklahoma City at around 1:50 am. What was even more disappointing was that none of the crew members acknowledged, let alone apologize, for the delays. These delays were not due to weather and were only due to operational/mechanical issues on the part of Delta. As a former Platinum SkyMiles member, I valued loyalty with Delta. However, after having similar experiences in the recent past, I'll be switching my loyalty over to American Airlines going forward. This was a highly disappointing experience.

Love Delta. I'll take connections to stay on Delta even if another airline has a direct flight.

The main issue was the quantity of the drink. The hostess gave only half cup full of the soft drink. I was thirsty and was expecting full glass like every other time.

Delta always provides stellar service. I am always impressed and will try my best to travel via Delta if I can afford it.

This flight was the flight we missed due to deltas delay at our first airport going TO Atlanta.

Wi-fi was out for the whole flight. I pay a premium to fly Delta because it has wifi and because it was out I didn’t get to work on anything I wanted to. I’ll have to make it up later this week by spending less time with my family.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

It was good flight was smooth, little cold on the plane but other wise good.

I need to note that this flight experience was generally fine but the boarding situation was absolutely a mess and there wasn’t any actual priority boarding. I rated the experience poorly because I’m am genuinely so frustrated with the crew on United taking the baggage space in first class. This flight it didn’t happen, but the last few flights (when I ironically don’t get an opportunity to provide feedback) have been spoiled because upon entering the first class cabin as one of the first few seated passengers, the overhead bins are full and ‘crew’’ tags are on the bags of those taking space. I don’t intend to infer some sort of a class or caste system but it’s absolutely ridiculous that the crew takes the overhead storage above and beyond their most loyal and lucrative customers. They should not even have economy space IMO. And I’ve gotten grief when I’ve noted to the crew the ridiculousness of the notion that the crew (who are the last off the plane) should have priority over flyers who pay. I hope you find a way to convey this message to United because it’s happening with increasing frequency and I intend to find a way to expose the specific crew members who are doing this on a flight by flight basis. (And I have a day job)

Great flight and crew. Need more legroom and DO NOT allow seats to recline.

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

Bathrooms broken, Wifi not working, Direct TV stuck in a United credit card loop for whole flight

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.

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

Tired of being nickel and dimed for every little thing, especially carry-on luggage.

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day. See attached receipt. https://share.icloud.com/photos/0f5ns2AaeIr7w6t_uH1qfPBUg

Late start, late arrival and very uncomfortable seats. No legroom, no elbow room because the person next to me was fat. I had to press myself toward the aisle or be rubbing arms with them. As a result, I was bumped every time someone passed in the aisle. But I couldn't get away from the hip encroachment. Who wants to rub hips with an oversized stranger for over 2 hours? I'm not fat, just tall and larger-than-average frame so I need to leg room but it would be nice if other peoples' body parts weren't squeezing under and over the arm of the seating. Why should it cost me so much for simple comfort so United can get a little more profit?
