I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

They lost a bag and now our vacation is ruined

Boarding waiting outside in storm and rain is not OK

Flight diverted to Warsaw and passengers offloaded onto coaches whilst the plane took off again and flew to Gdansk…

Miserable staff did not want to be there. Very poor atmosphere boarding. Then just basic flight.

Good value for the money. Good leg room. Take off and landing very good.

Seats are very small, I’m not a big person, but the person beside me was using his seat and half of mine… and this person was a bit gross but not a lot…

How terrible! Extremely bad! I can not even wait for 5 minutes, because the Berlin airport does not work in the security facilities and can handle people. No communication, although we were assured by about 50 travelers that the airline is informed and is waiting for us.

They gave us chocolates twice (for whoever would like an extra chocolate - kids did!). I asked for an extra water, and I was given one. Crew was very friendly!

Flew on a relatively old Airbus A340. Must have been one of the tightest economy seats I've ever experienced in a 2-4-2 setup. Seat doesn't recline much, and you're basically sitting up-right for the entire 11+ hours. Meal service was curt. The hot/warm dish was half squished causing some of the contents to squeeze out and make a mess when it was tossed onto the tray. TV screen is small for this day and age, and the USB didn't work to charge anything either. However there are lots of movies and tv shows, so that was good.

Food was good! Crew very polite however when asked to adjust temperature did not help! It was freezing! Seats uncomfortable 😣

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(

It was a very full flight, makes it harder for flight crew.

My mother is 87 years old and has knee problems. I have reserved a wheelchair indicating that she is immobile. For her it is very difficult to walk short distances. On arrival in Frankfurt, I was called via my mother's phone, by the female employee who had my mother in a wheelchair. She asked me how many and what color suitcases she has, which I explained. I was very surprised when 15 minutes later my mother walked out with her cane and balancing with great difficulties assisted by a young couple who were pushing her suitcase. Where was the wheelchair and the airport employee? I find this to be a disrespectful and abusive behavior of elderly people. It also raises the question of professional misconduct of the airport personnel in Frankfurt i.e. the female employee who abandoned an 87 year old immobile person by the luggage lane. I would like to inquire about the details i.e. name of that employee.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Boarding delayed 1.5 hours. Ended up sick because of all the delays and lines waiting around airport and boarding.

my flight was cancelled. next one scheduled 2 days later. no hotel provided. worst airline experience ever

Crew was nicer to some people than others for no apparent reason. I had to get an older lady’s attention because she was too busy talking to passengers.
