As to what happened, neither avianca nor atrapalo helped and we got no compensation. Even though flying business class, as there were no direct flights due to a pilot strike, they did not do anything to make the situation better. We didn't pursue it further.
If someone adds an answer elaborating what could have been done or what rights exist, I'll consider accepting that, until then the question stays open as I have no theoretical basis for my answer.
