I always fly Lufthansa and find it one of the best airlines. They take good care of passengers. Staff is excellent. However I would like to flag some improvements which could be considered. Water is basic and it's not such a big deal to provide a water bottle to each passenger. It's annoying to ask for it again and again. Entertainment system needs drastic improvement. For frequent flyers, there is nothing new for months. Vegetarian food is so predictable. Some alterations would be highly appreciated.
