You can also add your frequent flyer number to a ticket operated by one of the airline's partners. If you have elite status, TSA PreCheck, or Global Entry, it also alerts the airlines of the benefits that you're eligible to receive. This tells the airline which loyalty account to credit the miles for your flight. Once you've created your account, be sure to use your member number every time you book a flight with the airline. You must sign up for each airline's loyalty program to earn miles from that airline. Doing this creates a member number that you can use to earn miles and a profile that expedites booking flights through the airline's website. To earn airline miles for your flight, the first thing you must do is sign up for your favorite airline's loyalty program.
