Not enough veg food for passengers. I actually did not get veg food and starved the entire flight duration.

Not enough veg food for passengers. I actually did not get veg food and starved the entire flight duration.

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

The crew on my Frankfurt to Chicago flight were outstanding!! Friendly, helpful and worth taking the time to write an excellent review on their behalf. I would fly Lufthansa again just because of their warmth, kindness and humor!

Overall, the service was excellent, the crew verry professional, and departures and arrivals were perfect.

in athens they helped me with my dogs and they solved all my issues excellent service outstanding

The staff were so very cheerful and happy! It really made my day to encounter such chipper folks throughout my journey

love the crews and my only problem was the delay at Frankfurt was very bad. I have travelled with Lufthansa for over 30 years now and this was cost me some planned business appointment

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We had the best help ever from the airport workers who helped us check in and get our luggage through even though the checkout was closed. We had gotten so lost that a 90 minute drive became 3 hours. They were fast and courteous and even helped with our rental car. Thank you to them!
