good in general food is just snack and beverages (same snacks all the time) could you try to change them?

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.

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

One of the best crews and best flights I’ve ever had! Really great experience

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

Connection times always good online, but not in reality when first leg is delayed (2 out of 2 times this trip).

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.

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.

Both my flight where delayed Had 25min to make it to my transfer flight

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!

The flight from DFW to SAT started out with a 2 hour delay. It was a five hour delay with no real explanation as to why. In addition, the time of arrival kept changing from 10:00 pm to 11:00pm to sometime after midnight. Driver picking me up in SAT was as confused as I was. Flight attendants were patient thank goodness since folks were a bit upset about a 2 hour delay that stretched into 5 hours.

Flight was good- arrived early ! But ticketing with Underpricer and Kayak was poor at best- unnessacarily difficult due to how the ticket were issued

Flight attendant, forgot her name, was in front cabin, she was great

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

It was a 3 hour flight from Dallas to Missoula. The aircraft did not have power plugs, internet or in-flight entertainment. When boarding, one flight attendant was "somewhere in the airport" so delayed the boarding process (not coming from another flight) although we did take off on time and landed early. In flight there was little to no service - we got the standard beverage but no real connection with the crew which feels unusual for a 3 hour flight. A passenger needed help stowing her bag and got no assistance, and actually some passive aggressive comments from the flight attendants about "she needs to remove the extender" and "she'll have to find a place for it". I have seen others be helpful and put a bag in the closet, or support assistance as the boarding door was already closed. Just not a great experience considering the cost of my round trip ticket {$1000}.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

You were more on time than United. I'm so over united delays.

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
