I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

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.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

Delayed take off but I think they waited for passengers.
