Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Flight was delayed. Can happen. But the info on the website and app said that flight was cancelled which was not the case.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

Quick and efficient as always. Air France managed to loose and damage my luggage that never made it onto my KLM flight.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

It was nice to be on a legacy airline, people try at least.

The Columbus-based WestJet crews that cover Delta commuter flights between LGA and CMH are excellent - this team included. Our flight today landed 40 minutes early, which is unheard of when flying out of LaGuardia. I've flown with the same crew in more challenging conditions, and they always rise to the occasion with helpful communication to the passengers so that we may manage expectations.

Easy on easy off and the staff onboard were wonderful. Left on time, arrived a bit early.

Weather in Atlanta necessitated an hour's hold on the tarmac before we could leave Detroit. The plane was packed, and I expected some surliness. But no! The crew was fantastic (jovial even!), responsive to people's needs, and kept us informed. Consequently, the passengers took the delay in stride, and what could have been an ugly situation turned out to be no more than a minor inconvenience. The crew were the stars here.

They did everything right and everything happened right on time.

We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

My flight was delayed and I got back around 3.5 hours later than expected. I had to get a new connecting flight

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

The Atlanta airport had thunderstorms, which caused our flight to be delayed by multiple hours. Once we were able to board.the gate agent was rude and was trying to rush us onto the plane because the team in the plane was about to run out of hours once we were all aboard the plane they ran into an issue where the catering truck was filling up the back of the plane and they left and had to come back because they didn’t fill it up all the way, causing even more of a delay. My seat was very tight. I didn’t have a lot of legroom overall this was a miserable experience.

Flight delayed due to ground hold. Republic airways did a great job.

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

Flight be on time would be a good start. Then train your flight attendants to be attentive and friendly. This time they completely forgot my row for the measly snack! United, do better!

United to needs to use their best planes for long flights like Guam to Hawaii with STARLINK on it

I would have preferred a flight voucher and to hop on a different flight. Delayed over 6 hours.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Seats could be more comfortable, food was plentiful and good.

Onboard staff was courteous, helpful, responsive and friendly. The boarding process was disorganized, poorly communicated, and disheveled. Gate agents were yelling instead of using the PA system, didn’t communicate the timing delay of our flight, and created an atmosphere of chaos rather than order and communication. As far as I know, there was no reason for their. I would hate to see how it operated under extreme conditions. I’ve never seen United Airlines operations in such a state.

Baggage claim signs were not updated with my flight information, so I had to guess. The app wasn't updated either.

Lufthansa seats were much more comfortable than United. While they had about the same video selection, Lufthansa didn't put advertisements in with the movies like United did. And the Lufthansa food was much better than United.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

Short flight, but no drink/snack service. The flights both going and coming were delayed.
