In 2026, the primary way to prove your Star Alliance Gold or Silver status is through your digital boarding pass, which should automatically display the Star Alliance logo and your status level (e.g., "SA Gold"). This is triggered by your Frequent Flyer Program (FFP) number being correctly attached to your booking. If the logo is missing, you must show your digital membership card via your airline’s mobile app (such as the United, Lufthansa, or Singapore Airlines app). While physical cards are becoming rare, they are still accepted. For lounge access, most 2026 lounges use automated scanners; if the scanner rejects you, showing the "Status" screen in your app along with your same-day boarding pass on a Star Alliance-operated flight is sufficient. If you are using a "partner" lounge (e.g., using a United Gold status to enter a Lufthansa lounge), always ensure you have the app-based digital card ready, as some systems still have trouble syncing status across different airline databases in real-time.
