They delayed my flight all day but didn't try to reschedule me until all other options were gone. Ended up on a red eye. Not happy. Lesson learned, don't book the last flight from SJC to RDU.

They delayed my flight all day but didn't try to reschedule me until all other options were gone. Ended up on a red eye. Not happy. Lesson learned, don't book the last flight from SJC to RDU.

Flight was delayed again. I fly out every other weekend and lately the flight is delayed 3 out of five times 🤷🏻‍♀️

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

The last 3 flights between BWI and BDL canceled the beverage service mid- way. Just say up front that the fight is too short. Thanks!

It was okay. The plane was delayed from earlier in the day, but they kept updating the departure time, sometimes later, sometimes earlier. That was stressful. Once we finally got on and took off, it was fine. I was supposed to have a connection in Chicago to Los Angeles, and the time for so late I was rebooked to arrive in LA 3 hours late. The departure time to Chicago later became early enough to have taken my original connection and arrive earlier but that wasn't an option.

It was fine. For some reason the flight was much longer than usual. It may have been explained, but I had noise cancelling earbuds on and missed a couple of announcements. The crew was fine, but there was a flight attendant who kept telling dumb jokes, occasionally one I found distasteful. This was my second time with him, but luckily it was a late flight so he didn't do as many. But I heard all of today's jokes twice, which was two times too many. Good takeout and landing.

Boarding good… although I wish SW had another seating system. We had to rush the beverages as the flight was only 50 minutes. It seemed to take forever for my husband to get the wine he ordered, and my coffee. We were then told to drink it like we were in collage, as landing was soon…..

Paid for early bird. Basically paid for nothing. Would have been in the same spot regardless since the entire plane family preboarded between A and B. If they can’t give you A they should be required to refund the early bird fee. Also I don’t know what the issue is with the flight attendants but their attitudes need to change.

Would have liked screens on the back of each seat.

The boarding process of Southwest and the “first come first serve” seat selection is very difficult and prolongs the actual boarding process as people figure out where to sit.

Aircraft without problems that leave on time, not 2 hours late with last minute gate changes across the terminal

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

Delta flight was on time, seats were comfortable, and crew was nice.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

It's OK. Engine was noisy. The flight was super late. I mean 4 hours late. That is unheard of.

We sat on the tarmac in Denver for over 30 minutes because a plane was in our gate. The pilot kept saying it will just be 5 minutes or less. However, we sat for over 30 minutes. Experiences like this make customers not trust what the pilot is saying.

Service was slow Flight was very loud at back of plane

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)

Seats needs to be wirer and food is very poor

Pretty much the exact same comments for this flight, there was crazy weather!

I have been flying united for a long time but now I’m done

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

Overall a good experience, but no wifi available for free or for purchase and we got wet from condensation or other water source during descent.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

Flight was canceled after 5 hours of delays sitting at the airport

I’m still in Boston and I was supposed to be home yesterday at 2:30pm

Fort Lauderdale doesn't have Priority Security line so why was such option available for purchase? I need a refund back

1/2 full flight, nice and comfy flight. On time, good service

Both ways the people in the rear section of the plane were forced to check their carry on bags. I would understand this if the size and number of bags were not limited, but I do not understand why there is not room for one small overhead bag per person, even if the flight is full. I could watch the baggage handlers loading the extra luggage from my window and I’m pretty sure mine wouldn’t have survived undamaged, even though it is new and sturdy.

Fabulous! This was the first time we've flown with JetBlue and the entire experience was flawless!

Like the variety of entertainment options. One crew member was a little on the rough/rude side. Boarding was a mess, attendants didn't do a great job of helping with the luggage storage and it delayed us a couple of minutes.

Horrible. Flight was cancelled, jet blue app not working to rebook, no phone number available to call Jet Blue, 400 ish people in line for the help desk, stuck in Boston for 2 more days had to book new flight with a different airline and still not sure if I will be able to get any refund.

The flight was delayed after already taxiing from the gate due to a malfunction. After 3 hours we were told the flight was canceled. The next flight available was Sunday. My daughter and I stayed overnight in the airport due to this issue. I was given a $12 meal voucher. Unacceptable

The pilots were awesome and got us there early. Great landing too. No complaints on the flight. Service - a young cabin crew woman was terrible as she seemed to hate her job and never smiled. Why do they hire people like that? Terrible. The cabin crew lead woman was wonderful - very professional (and more mature go figure)

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

The crew were diligent about ensuring that our pet dog remained in his carrier for the entire flight, as is their mandate. I wish that mandate was changed so that our poor, scared pets can be comforted during a flight, whereas service animals get to stay out and about for the whole flight. Thank you.

My feedback from the trip to Columbia to Chicago was meant for Chicago to Denver.

The boarding and flight announcements need to be honest and accurate. These were not. While flight delays cannot be avoided, please. be honest with the passengers in informing us about the timing of the delays. Deceptive delay times is not good business. Deceptive and/or grossly inaccurate boarding times are not good business either.

the first flight smelled like urine Ac didn’t work pathetic experience

The flight was delayed multiple times. I was autobooted and placed in the center seat in the last row of the plane.

Am still mad at American airlines. You should know it's us travel nurses who are your customers and you treat us like nonsense it's not ok. American airlines took my money, no refund for whatsoever. A trip that was of 466 and I paid 466 and 833 then they chose for me where to sit and refund my seat choices and gave me expensive seats for 79 USD. Kayak doesn't help at all after booking you are on your own. Skyscanner is better

Terrible experience with baggage claim at CLT. Posted as arriving at belt 4 and screen there showed the flight. Waited for over 1.2hrs before someone randomly came by and said the bags for that flight had been dropped at CD1 an unknown time ago. There was no notification in the app, on the screens or by any airport personnel prior to this time. Waiting 1.2 hrs after a 2 hr flight for a bag you paid $40 extra to check is infuriating and disappointing.

On the new 319 NEO? seatback entertainment system did not work even when the flight attendant rebooted it. At least I had my cell phone to connect with wifi.

Delay. Flight was delayed in Washington.knew that connection was impossible as not enough time to switch terminals. The steward would not let me stay the night. So forced to Dallas.late night, after 10pm.hotel checkin was one hour. Passengers lined up only one girl to checkin at comfort inn. No food availability at that time. Had to leave early at 6:30 am to catch a flight at 8:45. Stressfull.
