Last few years I didn't not have great experience with United Airlines.

Last few years I didn't not have great experience with United Airlines.

The airport gate in Lyon was an insult to human dignity…. Shame kn the French authorities

Booked economy. Seat felt like it was a bit more roomy than my last trans Atlantic flights. I had a nice person sitting next to me. Everything was as good as it could be considering you are 35,000 feet up in the air and in a metal container. Beers, wine, food were all readily available. Plenty of movies and shows to watch. Friendly flight staff

We were delayed three hours from Montenegro to Vienna on our outbound flight and then rebooked an extra leg on our trip to the US. Our bags, which Austrian made us check in in Montenegro even though the flight was barely half full, didn't find us for ten days. Then, when we asked for compensation for the delay we were given the runaround that the flight originated outside of the EU. Next time we fly Turkish Air.

Most of the crew members were rude, flight arrived late and we missed our connecting flight, they damaged my friends suitcase so badly that two wheels had been destroyed.

Loved the courtesy and punctuality. Very professional and most importantly on time.

I did wish they would give us the entire little bottle Bailey's instead of just have 1/2 bottle at a time

My layover in Vienna was supposed to be 35 minutes but because my flight was canceled I had to wait in the airport for an additional 8 hours.

Very limited legroom in a 10 hour flight.very old plane.

The flight was delayed for 30 minutes with no apparent reason. There is no entertainment at all, and no USB or electric outlets for charging your phone or tablet.

The flight got delayed 3 hours from Montreal and we missed our connecting flight so it was a long journey

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

The crew and especially Patrick were amazing. Very helpful, kind and accommodating. I’d be happy to fly with this crew for all my Europe trips!

it was great the cabin crew were polite and detail oriented.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

United lost my travel information and canceled my original flight. I had a seat assignment but was refused the booking. I had to prove that I went to Germany on United Very concerned about security that no one recorded my passport from Cleveland to NY and NY to Frankfurt I arrived at home at 12:30am on Saturday instead of 8pm I expect a full refund from United Please provide information to assure compensation

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

It was a short flight. Plenty of room on the plane. It was also extremely clean.

Efficiency of staff, and comfort and cleanliness of aircraft was all great. Maybe a hot drink without payment at that time in the morning would be good!

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.
