To check your frequent flyer miles in 2026, the most direct method is to log into the airline’s official mobile app or website using your membership number or email address. Your current balance and "Elite Status" progress are typically displayed on the main dashboard. If you fly with multiple airlines, a "pro-tip" is to use a third-party mileage tracker like AwardWallet, which aggregates all your balances (airline, hotel, and credit card points) into one view and alerts you when miles are about to expire. Additionally, you can find your mileage balance at the bottom of the monthly e-statements sent to your registered email. If you believe miles are missing from a recent flight, most apps now have a "Claim Missing Miles" feature where you can upload your ticket or boarding pass details to have the balance updated within 48 to 72 hours.
