In 2026, most major global airlines (such as United, Delta, American, and ANA) allow you to check your standby status in real-time via their official mobile apps or websites. Once you are added to a standby list—whether for an earlier flight or an upgrade—you can view your position on the "Standby List" or "Waitlist" screen. This screen typically shows your place in line (e.g., "3 of 12") and how many seats are currently available in the cabin. On some airlines like ANA, as of May 2026, a "Standby Reference Number" is issued, allowing you to track your status even before you pass through security. However, while you can check your status online, you usually must still be present at the gate area to finalize the boarding process if a seat becomes available. Many airlines now also send a push notification or SMS the moment a seat is cleared, allowing you to bypass the gate agent and go straight to the boarding door with a new digital boarding pass.
