I know Southern Winds is a "partner" of GP. Mostly within Argentina.
I tried to get a flight to Mendoza using GP miles 4 weeks ago. I gave them a wide window of travel dates, as I will be in Argentina for most of Feb. They took abot 2 weeks+ before they got back to me saying "sorry, no Award seats available". Note this is 5 months out.
Has anyone had success in the past year getting SW award travel with GP? How did you go about getting the reservations?
By the way, anyone going to be in B.A. during Feb? Buy you a drink in the Recoleta.
