Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

First The flight got delayed because one of the crew members was late and we couldn’t board until she arrived. Then we all boarded and got held in the tarmac for another 30 min.

My service light was on 15 minutes before I had to get up and find a glass of ice. And I was in business class. The meals were not for either my wife and I. She did not eat the entire 10 hour flight and I managed a bowl of soup. I was expecting much more from business with what we paid.

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

It was delayed but other than that it was great.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

There was supposed to be a meal served, but there wasn’t and the major toilet was out of order

At first, we were on the runway for about an hour, literally. The Captain did explain that the Control Tower just had a change shift (sounds like an unrealistic excuse) and then that we had to change a runway. A regular economy seat is made for 12 yo twiggy. I understand Delta wants to push for an upgrade, but after sitting in a Comfort seat and in First class. I would say First class is not worthy of my money. The landing was delayed because of the weather in NYC, I don't hold that against Delta, of course. The Captain did alert us to that upon takeoff in Vegas and again as we reached NY.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

It was perfect! I've never flown with United before, but I definitely will in the future

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

The flight attendants were great, I joked with one I can’t remember her name, a blond, really sweet. I thought it was run well very professional. This was great i survived Spirit, I know for which I speak.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

Seats are outdated. Entertainment relies on personal device. Boarding was delayed due to inaccurate passenger tracking, resulted in late arrival at Reno.

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

Overall all good with the flight. Appreciated the extra spacious upper storage for (vertically standing) carry on. Efficient crew, on time departure... What could it be better is the in seat power. No one was working in our row. We were counting on the in seat power to recharge our battery depleted phones. With the dependency we have in our mobile devices nowadays, the availability of in seat power is a must....
