San Francisco to Frankfurt in First Class. Lufthansa uses the United Global First Lounge at SFO, a pleasant, but unremarkable, space. Lufthansa's A380 First Class cabin has an 8-seat arrangement. I was in 1A, right in the front and on the second deck of the aircraft. Upon entry into the cabin each First Class passenger is given a personal locker to store carry-on luggage. The seat was extremely comfortable, with a modicum of privacy provided by an adjustable screen separator. Two spacious washrooms serviced the First Class cabin. Where Lufthansa's First Class product excelled was in its exceptional onboard service. The lady flight attendant assigned to me was highly professional and personable, anticipating my needs as the flight progressed. Turndown service with mattress and blanket was provided when I wanted to sleep. Since I don't drink alcoholic beverages there's nothing to add to on that front. As for the food, this is as good as it gets on a flight, but I like to eat light. After landing, I went to the excellent Lufthansa First Class Lounge at FRA, an oasis of calm, and after a relaxing couple of hours was driven in a limousine via the tarmac directly to my outbound aircraft.
