Lufthansa is a core founding member of the Star Alliance, the world's largest global airline network, which means it shares extensive codeshare agreements, frequent flyer benefits, and lounge access with over 25 other airlines. Major partners include United Airlines, Air Canada, ANA, and Singapore Airlines. Within Europe, Lufthansa operates as a group that includes Swiss International Air Lines, Austrian Airlines, Brussels Airlines, and Eurowings, often sharing "metal" (aircraft) and schedules seamlessly. In early 2026, Lufthansa significantly expanded its partnership with Air India, adding Austrian Airlines to their joint network and opening nearly 100 shared routes between India and Europe. Additionally, Lufthansa maintains strategic joint ventures with United and Air Canada for transatlantic routes, as well as with ANA for Japan-bound traffic. Travelers flying on a Lufthansa ticket may find themselves on any of these partner carriers, allowing for a vast global reach that spans nearly every major commercial hub across six continents.
