I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.

I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.

Everything was good. However, the selections of movies and TV shows were boring and unexciting. It was disappointing.

Personal demeanor not good on flight returning to LAX..Great and superb on the way to Portland

Very helpful with my mother who needed a wheelchair at both ends and everything went as expected

The flight was great, the crew was great. Our complaint was that there are no TV screens built into the seats. We used our tablets but drained my battery just watching a movie. The movie and TV selection were okay but not great.

Plane was delayed and got me in past bedtime. But more importantly, my tsa precheck number wasn’t on my ticket so had to deal with the general line. Oh well, guess the delay helped that situation.

The Crew was super nice but the plane was subpar at best. Filthy in some aspects. Internet only worked half the time and not with everything.

They were all very kind, but misinformed. We came from Idaho to Spokane, Washington and were told that my husband and I could get passes to sit with William until his flight took off. (William has special needs.) When we got to the airport we were told only one of us could sit with William, so my husband and I were separated for 2 hours as I sat with William. What is WORSE . . . is I asked for a meet and assist in Portland and they NEVER showed up. NOR did they call me to tell me they hadn't met him. William's grandmother in Portland is disabled and can't walk into find him. Fortunately, some kind citizens helped him to find the meeting point with me on the phone in terror. I have a heart condition, complete with prior heart attack, this type of customer service is UNACCEPTABLE.

Could have had more of a beverage selection than water and apple juice.

Crew was overly aggressive with rules enforcement and not friendly in general.

Fine except the person next to me took up her seat had raised the arm divide so she spilled into my seat. because of her size. Fortunately no one was in the seat on my right so I could use part of it.

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

Crew was friendly Love the entertainment in the seat head rest.

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

This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Delta is a cut above the others in customer service.

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

A bit rush for transit. Food and entertainment are not available

So far so good but food and entertainment are not available for this flight

Multiple delays and not straight answer from the United team

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

Paid $35 and not able to access the internet at all.

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Flight was delayed bc of mechanical issue. New plane had different configuration so some seats had to be switched. They called all passengers who needed new boarding cards. They did not call us so we thought our seats were the same and fine. When we boarded they informed us our receipts had changed and we are now all sitting separate and in the back row. Both my daughters had meltdowns and started to cry and once we got on the flight, we figured out how we could sit closer to each other, but this was very upsetting.

Took off on time and successfully avoided weather that looked to be a problem along the way
