awesome shots!
my mum worked for copa airlines when we lived in Colombia, she flew that same route many times when she was sent for training to panama city... i like the scenery...but the real Colombian scenery is breathtakin. try downloading the bgl's available at AVSIM, they cover colombia and surroundings, worth the time

Copa was bought by continental airlines, and the whole point of the new paint jobs was to "confuse' people bewteen copa and continental. mum was chosen from SKBO station to go to seattle along with other copa employees from around latin america to recieve the first of the 700 series boeings.
great shots man! keep'em coming.
