Northwest Airlines and Paypal

[aethelbert]

I'm trying to book a flight on Northwest since I received an electronic voucher from them a while back for submitting a comment. According to this (http://www.nwa.com/features/paypal/) page, they accept paypal at nwa.com. However, I can't for the life of me find out how to pay via paypal. Whenever I get to the payment section, there's no option for it nor is it mentioned on the page. I've tried it with both Delta and Northwest flights, but neither gives me any success.

Has anyone on here used paypal with Northwest? If so, what's the secret?

Thanks
