No food or drink, Not much conversation with crew. They didn't come through to check on people. There were no charging stations or wifi to watch movies. It was like being on a bus in the air.

No food or drink, Not much conversation with crew. They didn't come through to check on people. There were no charging stations or wifi to watch movies. It was like being on a bus in the air.

This flight was originally delayed by ~45 minutes; which is fine. However, there were additional delays due to late offboarding of the prior flight, unclear issues with the boarding process, delays on the tarmac, and exceptionally long taxiing. None of these issues were communicated proactively. Additionally, the flight had exceptionally rough turbulence, which led to a very uncomfortable flight and no traditional beverage service. Again, this is understandable, but it was not communicated up-front by the flight team.

Gate agent showed up 20 minutes before boarding and was not at all friendly. Had to take this flight due to the one on the day before being cancelled and any later options were already full with long standby lists. Despite having paid for Delta Comfort seats, Delta did not allow me (or anyone) to choose their seat. The agent assigned them for everyone just prior to boarding. Self seat selection was allowed on the original flight. Flight staff was great - very friendly.

Two delays on two separate planes with parts they could not easily find and replace.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Flight was 3 hours late so only had an OK 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.

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

I didn’t have a seat assignment and my seat was very dirty on the flight from Frankfurt to Budapest.

Turbulent taking off & landing to Dulles from Raleigh. Flight from Dulles to Tokyo very good!!

Food is terrible. Flight is outdated and seats are not comfy.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

Boarding was easy. RDU gates can get crowded, be prepared to be patient. Flight was smooth, with excellent service. Pilots really provided a lot of visibility into flight details. Plane and seats were clean and serviceable. TY!

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

Got automatically assigned middle seats unless you fork out extra money for a seat assignment, not impressed.

Late by nearly 2 hours due to taking that long to change a tire on the plane.

The boarding on this Air Canada flight from Toronto to Barcelona was a complete mess. The ticket was written under United but they were actually Air Canada flights. We went from one end of the Toronto airport to the complete other side.
