1. Provide your WorldPerks account number when making your travel reservations. When flying on Northwest or any Airline Partner, you can only earn miles in one frequent flyer program. By providing your WorldPerks number, you are specifying you want to receive WorldPerks mileage credit.
2. Verify the airline is a WorldPerks Airline Partner by using the chart below.
3. Retain your ticket receipts and boarding passes until the correct flight mileage is credited to your WorldPerks account. A mileage credit request may be filed if miles do not post to your account after six to eight weeks.

In addition to the base miles earned on your flight, you will earn a 50% Elite qualifying bonus for tickets booked in Y or B class on Northwest, and full coach fares on Elite qualifying Airline Partners. This 50% bonus will count toward Elite qualification and not toward banked mileage.
