You can find flight numbers on your boarding pass, flight ticket, or booking confirmation. One of the most direct ways to locate your flight is to see it near the top of your physical or digital ticket.

Once you are actually physically on the plane, finding the flight number requires looking at specific digital interfaces. The most common way in 2026 is via the In-Flight Entertainment (IFE) screen at your seat; the flight number is usually displayed on the "Flight Map" or "Flight Info" tab, alongside your altitude and ground speed. If the plane doesn't have screens, you can find it on your digital or paper boarding pass, which you should keep handy. Additionally, most airlines now have onboard Wi-Fi portals (even if you don't pay for the internet) that show a "Flight Status" page with your flight number (e.g., UA123 or LH456). If you are looking at the exterior of the plane, the flight number is not painted on the fuselage; only the "Tail Number" (the aircraft's registration) is visible there. When in doubt, the flight number is always listed at the top of the "Welcome" announcement on the cabin's overhead monitors.
