Now that it's February, Northwest resets their Worldperk's program for everyone. It's been nice because having Gold status this year means I get upgraded to First Class just about everytime I fly, at least for now. I'll probalby fly between 50-75k miles this year, most of it with Northwest. Northwest has the most generous of the frequent flyer programs out there, but their planes are the oldest out there, and their stewardeses aren't the friendliest.
