Northwest Airlines is offering 25,000 miles if you sign up for a Worldperks Visa.

Here’s the skinny:
* 5k bonus at signup
* 5k bonus if you spend $500 w/ Northwest (flights, club membership, etc) by 10/31/02
* 15k bonus if card is open and in good standing after 15 months
= 25,000 miles.

Fee for the “classic” card is $55/yr.
2 years = $110 = $0.0044/mi as long as you’re purchasing $500 from Northwest in the next 5 months…
Call 1-800-360-2900 and ask for extension 2644.
Expires 7/15/02.

Note that the credit card I recommend most often for earning miles is the Starwood American Express, because points transfer 1:1 into most airline programs and you get a 5k mile bonus for transferring 20k points — equivalent to earning 1.25 miles per dollar on all purchases.
