Absolutely the worst food I've ever had on any flight. Otherwise, the flight is OK - just your regular transatlantic economy. Condor should stop saving pennies on meals. They save a penny, lose a dollar.

This is truly the worst travel experience of my life. The UK ETA program had a technical failure, and I was stuck in limbo for 24 hours, unable to board my flight and unable to navigate anything in my itinerary. I had to rebook an entirely new flight and I’m now out doubled the money. Unconscionable.

OK, would prefer some meat for dinner, not just pasta although was tasty. There was only one dish, no choices

Flight delayed with no explanation. Boarding was confused (proceed to plane, go back to waiting area).

Accommodate the passangers at the gates. They only allow groups 1-3 to sit near/at the gate. We had to wait 3 HRs an had to look for a seat far away from the gate. Other than that was like other Airports.

It was a great experience. The aircraft is a bit dated but other than that it was great.

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

Short flight. Bare bones and kinda seeming like an older plane. But got me there on time and that's what counts. Perfectly fine flight all the way from start to finish.
