Sucre is beautiful, beautiful, just beautiful. Fly there! I flew on Jun28, 2010 on CP
-SRE, and for 2 adults and a child we paid 211USD in total at the airport 3 hours before the flight. It was dirt cheap, and the flight is over magnificent landscape.
Unfortunately, there was some problem with Aerosur processing Mastercard, and I was unable to purchase tickets online; everything went right before the payment, I was issued ticket numbers, but my card just was not processed. You will not regret this flight!
There were 6 people cabin crew (huge for this size of an aircraft), and they were very nice.
In La Paz, one could board via the rear steps. A unique experience. We did that to the annoyance of my wife as we got row nine (?) and had to pass lots of people inside the aircraft
I was allowed to enter the flight desk and the pilots showed my child around after we landed in Sucre. Try to ask for a jumpseat, that's one of the best places in the world for that.
GO FOR IT
