Enrollment From time to time, the data you have furnished to Northwest and KLM may be used to bring you relevant and valuable offers from WorldPerks partners. If you do not wish us to use it for this purpose, please contact the WorldPerks Service Center. The WorldPerks Free Travel Program is open to any individual with a mailing address in North America or in any country that has not prohibited participation in frequent flyer programs, with the exception of countries in Europe, Africa, the Middle East and the Indian Subcontinent. Corporations or other legal entities cannot be enrolled as members. Only one person may be enrolled per WorldPerks account.
Membership is non-transferable.
Retroactive credit will not be given for flights taken prior to enrollment. Earning Flight Miles When making flight reservations please confirm the airline is a Northwest WorldPerks Partner airline. Northwest is not responsible for notifying members of changes in partner participation in the WorldPerks program. You must actually travel to earn WorldPerks flight mileage. Miles will not be awarded on unused, forfeited, fraudulent or refunded tickets, or on additional tickets purchased on the same flight under the same name for any reason.
