I'm assured to re-qual for Gold by next week, but after reading the WP booklet I'm not sure what the big deal is about going for Platinum. you get a 125% vs 100% miles bonus, which is nice, I suppose, and a better shot at upgrades, but other than that, is there any particular reason to make an effort to reach Platinum? I've been very pleased with Gold and have only failed to be upgraded once this year, so the only draw might be the miles. it'd be nice if NW gave out some system-wides or something extra for Plats, sort of like what UA do for their 1Ks, for international travel.
75K miles is a lot less than what UA and AA and (I think) DL require for their top tier. maybe that's why the benefits aren't that great. maybe a Plutonium level at 125K or something wouldn't be a bad idea?
