Premium Economy was very comfortable. Flight staff was cheerful and helpful.

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

I’m glad the bus waited for me to connect me to my next flight since we were delayed. Flight was good.

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

Good but entertainment system was not easy and very buggy

There is more space in this economy seat. It felt like a better layout, not so cramped.
