Levels

• The WorldPerks program consists of four membership levels. A member's level of membership is determined by the number of Elite Qualifying Miles earned within one calendar year.
  
  

Elite Qualifying Miles

• Elite Qualifying Miles are WorldPerks miles earned by flying on Northwest, KLM or Delta Air Lines flights. Bonus Elite Qualifying Miles are credited to the accounts of members who fly in First or Business Class.
  
  

Earning Miles

• WorldPerks members can earn miles by flying on a Northwest Airlines or WorldPerks airline partner flight, or through a Global Alliance partner. Global Alliance partners allow members to earn miles for hotel stays, car rentals and retail purchases.
  
  

Award Travel

• WorldPerks members can redeem miles for domestic or international flights. Members can book award travel for themselves or for someone else using their own miles.
  
  

Upgrades

• Members at the Silver, Gold and Platinum levels of the WorldPerks program receive complimentary upgrades to First Class when seats are available.
