Good timing thanks Matt, I have just spent a few hours trying to sort out out LPB-BOG-QIO. After dealing with all the quirks of the Lifemiles booking process ( and the usual fare increase as soon as you enter the passengers) I booked an L Bundle points booking and paid $85USD for row 2 seating (they appeared to be the best based on reviews) AreoLOPA has the most detailed info but leaves out row 1 pitch details. Anyway - got the booking and the seats for the first leg were not allocated (and not charged for) I only noticed this when I saw the CC charge. SO back I go and I has look at about 20 reviews and videos - most of which were conflicting. BUT when selected purchase seating - row 1 came up for free - go figure. If all of these arrangements stick and the plane actually flys on the selected date, it will be a reasonably good outcome as a redemption booking, based on the cash price of this particular flight. I cant say as much for other Avianca flights in South America, the value really varies.
I have been running down my points with them for a while now and there new (to me) 4 level "bundle" seems to be OK, but the fact that they charge $US50 to redeem your points, their clunky website, the changing prices and lack of availability most other places means that I will run out my points and never go back to lifemiles. the only other plus is that there seems to be the ability to book early and save around 20%
