I'm about to spend 4 months in Buenos Aires. I got a reward ticket SFO-EZE
(CO & Copa flights) without any problem (got a standard reward first class ticket!). I'd like to invite a friend who lives in London to come visit me and I'd like to give her a free ticket using CO miles. Is a London-Buenos Aires routing possible using CO partners other than Copa? I would think that a CO/Copa London-Houston-Panama-Buenos Aires routing would just be too exhausting, especially considering that an overnite is required in Panama City. Is a routing using one of CO's partner's like TAP possible?
