I bit a few weeks ago; probably 6 by now... I just sent in the companion certificate today for the voucher (an unnecessary step that they must figure some will not do). Per the stuff that I got, the voucher is only good on specific routes/cities. There was a decently long list of airports, but not the usual "companion voucher" that's good on any domestic route. I'll look for the paperwork tomorrow and let you know which cities it lists. I'm still waiting for my T&L magazine so I can cancel membership before the $20 charge hits.
