I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

There was a loud squeaky sound the whole time we were flying.

Had a broken tray in business class. Crew just shrugged it off.

Flight was late. Club was full. Experience is exactly what I expected.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Great experience overall. Check in at Austin was congested as they only have about 6 check in kiosks, one was broken, and there was a lot of Spring Break travelers.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Everything would be much better if Kayak stopped nosing into my business with Delta.

Everything was very good other than I had selected a specific seat when I booked the flight and they changed it once I checked-in the day before my flight. I was still in first class but lost my aisle seat for a window seat. Being tall, the aisle offers more comfort so I always select an aisle seat.

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

It took an hour to get my bag after landing. Not exaggerating

I liked that boarding and take off were timely despite a 15 minute delay due to weather. The pilot communicated with us the entire flight keeping us informed re: turbulance and slight delays on the runway after we landed.

I had a horrible experience with TSA at the airport. I had to go through TSA several times as there was some issue each time with a piece if clothing I had on. It was so busy & chaotic that I ended up forgetting my Apple laptop at TSA. It’s been days & I can’t get through to anyone to get useful info on how to get it back. I’m very angry because contacting lost & found shouldn’t be this difficult. Employees should know what is going on at their place of work. It seems no one knows as everyone’s answers are contradictory, or you can’t speak directly to anyone as the calls are automated. Very upsetting.

Everything was good instead change the gates! I missed my first flight because it was changed the gate and I didn’t know!

I didn't like the 2 hour delay and then mechanical issue once we were on board.

My experience with Eva sir was good except the long walk in LA Lex, that was inconvenient for my age,

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Realize ahead of a 6:30 am flight that you have a completely flat tire that needs replacement. They should have never boarded everyone. They kept us at the gate with the door closed for ALMOST but not quite 3 hours. The plane had been sitting there from the night before. At the 2 hour mark of sitting there, they came through with a bottle of water and cups. Never offered snacks. Never offered a real apology. People missed connecting flights completely. Absolutely no apology. Just yep you are going to miss your connection completely. I don’t know if you can get to your destination today. The new boy time there was a seemingly heartfelt apology was when they said they were sorry and then fifer everyone an opportunity for a credit card. It was so poor. Lucky for us, our funeral was not the same day as our flight or we would have missed it. All for an avoidable repair that could have been done before we even set foot on the plane.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

The WiFi didn’t work and the seats are too close together. Very uncomfortable.

So so. Terrible aircraft choice for that leg of the flight.

Fight crew was not very attentive and the bastions were gross!

Our flight was great we left Kona earlier and got into LAX almost an 1hour earlier as well. LAX AA is in repair so to get out and found our bus to get pick up was a bit confusing.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

I can say I will not be taking this airline again any time soon. Seat were uncomfortable and too tight. Lack of chair screen and little overhead space.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

For an over three hour long flight one pack of cookies was not enough.

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.

Over an hour delay in departure but I was notified beforehand. Another delay on tarmac upon arrival at LGA. We ended up departing the plane almost 2 hours later than expected

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….

See my previous comment which is mostly about our flight from Phoenix to SFO

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.
