With the addition of AviancaTaca as a Star Alliance member, I noted that this will be a very useful program for some.
They offer frequent bonuses on purchased miles, making their points cheap to acquire, and they offer cash and points award bookings as well.
At the time there was no complete award chart posted, you had to search route-by-route to figure out how much awards are supposed to cost. That has been rectified. Overall the chart is quite good, generally competitive with US frequent flyer programs.
They offer online award bookings, and some glitches (mostly in customers’ favor) have been reported so far (some destinations pricing in the wrong zone, other routings allowing getting off at a connecting city for less than the full routing costs).
I wouldn’t bank of those remaining, I’d focus on the program for the value that it offers. And if you do even better than that, congratulations.
