In an effort to draw more customers to its “My NWA Info” feature at nwa.com, Northwest WorldPerks is offering members the chance to win 10,000 miles just for signing up.

The service, which is free, gives members the ability to manage contact information and customize travel notification options. For example, by using the service, members can opt to receive an email, phone or wireless message with an update on flight status and departure gate.

Current My NWA Info members may also participate. Visit http://www.nwa.com/win for more information — you must register before July 18.

Once registered, you may play the game once per day. There is no limit to how many times you can win.
