Our original flight was on United Airlines but was code share changed to Lufthansa. Such a good experience when compared with several other long distance economy flights we've taken. The service was courteous and personable. The seats were only a smidge larger than normal but seemed to be much more comfortable and had a little more leg room. The food was above the normal economy grade in flavor and presentation. We were given plenty of snacks, drinks, dinner, refreshments, breakfast and good coffee. In addition, there were lots of entertainment offers, new and old movies, games, music and TV shows. The plane configuration was two seats/three seats/two seats wide which is a great layout for long legged people on a budget.
We would fly Lufthansa again.
