One of the best parts about being part of a frequent flyer program is earning miles, which you can later redeem for flights, flight upgrades, car rentals, hotel stays and more. You can also attain elite status, which may afford you privileges such as priority boarding and free checked baggage.

Tips for finding and remembering your frequent flyer number

• Log in to your frequent flyer account.
  Most frequent flyer programs let you log in with a username or email instead of a frequent flyer number. If you’ve forgotten your credentials, you can use the Forgot password link to get a password reset link sent to your email address.
• Keep track of your membership card.
  Some frequent flyer programs issue you a card that includes your membership number. If you keep this card somewhere safe, you can refer to it anytime you can’t remember your frequent flyer number.
• Check old flight bookings.
  If you’ve previously flown with an airline as a frequent flyer, look for your membership number on previous flight bookings or itineraries. Check your printed or electronic travel records and see if it’s there.
• Search your emails.
  Frequent flyer programs typically send newsletters and statements that may include your membership number. Go to your email account, type the name of the frequent flyer program into the search box and browse through the emails that come up to see if you can find it.
• Ask a travel agent you’ve used previously.
  If you’ve made travel arrangements through an agency, it may have your frequent flyer membership details on file. The same is true of online booking services; just log in to your account and see if the information is there.
• Check your eligible credit card account.
  If you have an airline credit card that earns miles for a particular program, your account should include your frequent flyer membership number. Log in to your credit card account and check the account details, or look on old statements to see if you can find your number there.

Bottom line

It’s easy to forget your frequent flyer number. Luckily, however, it’s also very easy to find it again. Keep it handy and use it whenever you book a flight, when you can earn miles and elite credits.

If you find yourself using your frequent flyer number often, you might benefit from an airline credit card.
