Yes, United Airlines is a founding member of Star Alliance, the world’s first and largest global airline network. United helped establish the alliance on May 14, 1997, alongside Air Canada, Lufthansa, Scandinavian Airlines, and Thai Airways. In 2026, this membership provides United passengers with high-value connectivity to over 1,200 airports in 190 countries via 25 partner airlines. For MileagePlus members, this means you can earn and redeem miles on partners like ANA, Lufthansa, and Singapore Airlines. Additionally, if you hold United Premier Gold status or higher, you automatically receive Star Alliance Gold status, granting you access to over 1,000 lounges worldwide, priority boarding, and extra baggage allowances on any Star Alliance flight. This integration is a cornerstone of United's international strategy, allowing it to offer a seamless "one-ticket" experience for complex global itineraries.
