Airline reviews

My school age daughter was not sat near me. We left almost an hour late. Therefore arriving late and missing another flight. Since it was not a connecting flight there was nothing Lufthansa could do about it. After the selay in take off and arrival we waited almost an hour for baggage claim. There was zero concern for my inconvenience. I asked if we could insure being seated together on the return. They stated no because we booked through Kayak. I typically love Lufthansa. This was very disappointing.

Great seats assigned and comfortable, movies are good, food is delicious, great experience. No delays and they prioritize boarding children with parents which is plus.

they canceled my flight and we’re absolutely atrocious and helping me rebook

My flight was canceled. New flight is 40 hours later and I still didn’t get the flight from Frankfurt to Zagreb.

Great service. The flight was in great condition and the staff was very cheerful.

Check in crew in Charlotte NC was superb. There were 6 of them plus what looked like a supervisor, helping to answer questions and keep things moving. Never saw so many check in crew. Then some of them showed up at the gate later for boarding. Great. The flight was mediocre. The seats were small with little leg room. The screens kept coming on when we were trying to sleep and wouldn’t shut off. I know we paid far less than first class but does that mean we should be shoved in there??

The accommodations are top-notch. The only negative was that both our initial flights were delayed, which caused us to miss one and almost miss the other. The staff immediately handled the missed flight and compensated us for the inconvenience.

Like: On-time performance Dislikes: Old aircraft with faded paint (A330), no WiFi availability, dismal food (dinner was a very poor selection, while "breakfast" was a joke!)

Food should be provided according to the passengers selection. In flight entertainment system must be updated with latest devices and applications. Proper over head headset must be provided rather than providing cheaper ones.

Very organized check in and boarding experience. Good crew very helpfull.
