Did not realize internet screen was hidden between seats and no info printed!!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

The flight was delayed for about 2 hrs. Other than it, it was good.

Advertised fruit trays with cheese, but only snacks handed out!

Good seats in Main cabin, excellent service and excellent landing

Knowing what gate to go to was such a issue I couldn’t tell on the app, they tell you what zone you are in but won’t give you the gate number, i almost missed my flight in Atlanta Georgia because of that, as soon as we landed my next flight was already boarding because our flight to Nashville arrived late, I don’t know how that works, but as soon as we got out I was told my next flight is boarding I had to rush lost few of my items, and when I finally got to the gate after struggling, I received a message about my gate after I already boarded, and no my tickets didn’t have the gate numbers either.

Food was surprisingly good but the WiFi was not great

Easy boarding with an extremely kind attendant. Seats were spacious and we had 3 seats for 2 people so we could stretch out. Comfortable air flow and very attentive and hospital attendants. Bathrooms and food were the only negative. Bathrooms were so small you could hardly get in and close the door. I don’t think an obese person would fit or a person with a movement disability. Food was the trending food for flights, nonexistent. We spent $40 getting sandwich and snack at airport for our 6 hour flught.

Not consistent with the food quality (I mean taste not freshness)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Sat next to a one year old. She crawled all over the place and made me laugh.

Not United Airlines' fault. It's ORL airport's fault.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

They did the one thing that really matters - got to Chicago early.

I liked the snacks and the flight attendants were friendly.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

Flight was late - I was downgraded from first class to coach

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Trip was smooth, good drew, average meal, almost cold coffee. Excellent landing. Did not enjoy going down the stairs, walking to the gate, walking up the stairs, going a long walk to the exchange gate, and going down the stairs again to be bussed all the way where we originally landed to take our next flight! Over all an average experience. Thank you.

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.
