My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Flight attendants very hospitable and friendly. Pilot flew a smooth take off and landing.

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled. No snack or drink on this flight.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled.

The wifi on the plane is great. The only issue that I have is that I prefer an aisle seat and on my trips this week, I was either in the middle or window. If we can work to secure aisle seating, I will be thrilled. Nice trip.

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

Everything went smoothly and we even arrived a little bit early.

First class and monitors weren’t working for mine & my husbands. Eventually fixed, but quite annoyed as we bought first class. Also, No foot rests.

Prior to takeoff, the pilot told us there was a possibility of not being able to land and going to Portland. Well that happened, we took off and then did 8 loops around Spokane before the pilot told us we ran out of fuel and had to go to Portland. So for a 35 minute flight we have now been on the plane for 3 hours (boarded at 6:50 am and landed in Portland at 10:30). Then, we just sat in Portland's airport with no updates of when we can start heading back. All of a sudden, our pilots and crew just left, leaving us stranded in a different city and state. We continued to sit in Portland until we finally got a new crew assigned and boarded the plane (This was from 10:30-2). We then sat on the plane for an additional hour before take off because they had to count us multiple times. We finally landed in Spokane at 3:55 PM. So a flight that should have taken at max an hour took us 10 hours and we missed the majority of the recruiting event we went for.

It was delayed but other than that it was great.

Got on the plane and sat there for an hour before departure.

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

They double booked seats, the gate staff changed my ticket as I was boarding she went over to the computer and changed it without telling me. She messed up an entire three row section for me and others. Other travelers were outraged but the gate staff were so rude, so condescending saying it wasn't their problem to solve. I would rate this a zero if I could. Will not fly Delta again I'll stick with United and American.

Comfort seating was on the tight side. Maybe it was a smaller plane(?)

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.

Timing, quality of service, promptness and courtesy of the staff

The flight was delayed by two de-icings. The seatbelt did not work correctly. It did not stay tight.

Hotter than Hades in August. Why, why do crews think that in the winter when we are already dressed for cold weather we need a cabin that is 82 degrees. Even the vents were blowing hot air.

Flight was delayed. De-icing took a while. When we landed had to wait for another plane to vacate our gate. Just an overall bad experience.

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

My husband and I recently had an unfortunate experience with Lufthansa. At the Philadelphia International airport, the ground staff refused to board us because we didn’t have a current visa stamped on our passports for Frankfurt. We completely understand that this was our mistake. we should have double-checked the visa requirements before our trip. However, the issue that upset us most was how the situation was handled by the staff. They told us they would mark it as “boarding denied due to visa issue”, but instead they recorded it as “no show”. Because of that incorrect entry, our return flight was automatically cancelled as well, which caused additional stress and expense. Mistakes can happen, but we expected more transparency and accuracy from a reputed airline like Lufthansa. It would have made a big difference if the staff had been more careful and considerate in documenting the situation correctly.

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

My husband and I had boarded the flight from Denver to Chicago, and one of the last passengers to get on the plane opened the overhead bin above my husband's seat and threw his bag out of the bin to make space for his own. He said, "Mine is bigger!" The flight attendant supported the new passenger. They didn't care that my husband has two artificial knees and must have the foot room in front of his seat to be able to fit his legs in -- and to be able to stand, much less walk, at the end of the flight. I have never seen this happen before, and it was a disaster.

Terrible. They wouldn't allow me on my flight on the 14th..

They are always late and seats was also not having working charger

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Excellent - explanations were clear staff was nice and flight was comfortable

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

Did not get the seat I selected and paid for.
