Lufthansa, officially Deutsche Lufthansa AG, is the flag carrier and largest airline of Germany, headquartered in Cologne. Founded in 1953 as Luftag, Lufthansa has grown to be the second largest airline in Europe in terms of total number of passengers. It has one of the largest airplane fleets in the world, flying to more than 200 destinations in over 70 countries, including 24 cities in the United States. Lufthansa is one of the founding members of the Star Alliance—along with United Airlines, Scandinavian Airlines, Thai Airways International, and Air Canada—making it a great means to earn air miles for frequent fliers. Cashing in these miles by upgrading to Lufthansa’s first class cabin is one of the most luxurious and comfortable ways you can take a transatlantic flight.
