There was an incredibly surly flight attendant that ruined the experience

First flight was delayed which resulted in missing our connecting. As a result class was downgraded to economy on a later flight.

Unprepared to rebook a flight of people. Uncommunicative. When I received updates in the app it was well after the announcement in the hold room. Offered a single $12 meal voucher, not enough for a sandwich at DEN, for a 17 hour delay. No one was able to explain their meal or hotel reimbursement policy for this cancellation, just handed a card to call the Help desk. My previous flight went through several delays and was finally cancelled, without explanation. The customer help desk closed while there was a long line. I then waited in line for a gate agent almost an hour while simultaneously on hold and trying to text with a remote Delta agent. Communicating with the text agent was almost impossible; they could not find any flights that got me back to my original city before the following evening. Kept offering itineraries that did not get me back to my origin airport or involved additional layovers. In 50 minutes on hold, never got through to an agent by phone. Finally spoke to one of the gate agents who was able to rebook on a red eye that had only one stop and got me back in the afternoon the next day, rather than late evening. Later by email, Delta offered 10,000 loyalty points for the inconvenience of the cancellation. The crew on the red eye flight were delightful. I don’t remember any food or entertainment on that flight.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

worst flight ever from Delta, it got delayed and kept on delaying..

Terrible. Four hour delay because Delta could not find crew to man the aircraft. Terrible communication. Terrible insight into the delays. One of the worst flight experiences I’ve had.

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

Plane arrived an hour before departure. Plane was completely boarded and ready for push back when they decided they needed to change a tire. 1 hour delay on the plane when this could have been done before we got on the plane.

Usual wait for over a half hour for a gate at Ohare. They tell you you'll get there early then sit on the plane and wait almost an hour

It was fine for the most part. But the volume on the announcements was way too loud, and the cabin temperature was chilly. We had the hardest landing I've ever experienced- I think it hurt my back, and the tires squealed when we touched down.

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Really delayed, no effort to support customers other than “sometimes we run late.”

The flight was excellent. Their was no service as we boarded, the flight attendants spent about 30 minutes just taking and not really caring that the cabin was about 80 degrees and did not offered any beverage to first class passengers or any passenger. The flight from DEN to ONT is not long but not under an hour, we received one drink and bag of chips if you were lucky. I was in first class…. I did leave my hat on the plane and it only took less than five minutes for a United rep to locate and bring it to me.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Good even though flight was delayed, the crew was prompt and efficient.

You could have been ON TIME! And I was miffed because I spent an extra $82 to get my seat and the steward put a woman from the back in my aisle for nothing because her movies wouldn’t work. I’ll try that next time and save $82!

Again a nearly five hour flight and pretzels is all the food you get and all you can drink water. No electric plugs in economy. Staff was totally not caring. Delta next time

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

Late boarding, had to check the bag even though there was space on the flight and I was I row 7

Unacceptable pre-boarding ticket issues. Paid for and reserved Mint seat approximately a month in advance. Checked in to flight in Mint seat 24 hours before flight. Shortly before flight, was bumped out of Mint entirely, even though other Mint seats were still available and for sale. Was told it was "operational", however seats were still available/being sold. Got to gate and they could not explain it, but the gate agent was able to put me back into Mint (however to a different seat). Nothing proactive done by Jetblue, I would have been bumped had I not arrived at gate early enough to have a helpful gate agent rectify. No explanations from Jetblue.

Diana at the gate was unhelpful which was fine, but she was also rude which I did not appreciate at all.

Forced to check bag, even though plenty of space in overhead bins. Did not appreciate having to wait at baggage claim to retrieve suitcase.

They lost my luggage and have ruined first day of my vacation. Still don’t have it. I have nothing. I also paid for a seat I did not get. They changed both our seats with no notice. Will never fly this airline again.

The flight attendant was snarky and the flight took off very late. I know it was an issue with air traffic control and the runways in Boston, so not really anyone's fault, but very frustrating, I missed an important meeting because of rgr delay. They didn't offer headphones to watch the TV, but luckily I remembered my own and was able to enjoy watching a movie.

Flight was delayed 3 hours. No food on plane besides snacks

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.
