To check your balance on the British Airways miles program, visit the company website, and click on Executive Club in the top navigation bar. Look for the Members Area section, and click on "My Executive Club" to access the login page. Enter your login credentials to see your balance.
The British Airways Executive Club allows you to log in with a variety of credentials. Log in with your member number and your PIN or password, or use your username in place of the member number. Alternatively, you can log in with your email address instead of the member number or username. If you have a business account, you must log in with your company's On Business member number along with the associated username and password.
Once you log into the Members' Area, you can view two Executive Club balances: Avios and Tier Points. Avios are the general currency of the Executive Club. Avios can be redeemed for car rentals, hotels stays and other rewards. Tier points designate your status within the Executive Club. As of May 2015, the four levels are Blue, Bronze, Silver and Gold. The higher your level, the more Avios you earn for each British Airways flight ticket.
