Like the trains in the US, the Cuzco airport didn't display gate information for each flight until roughly boarding time (airlines don't appear to be assigned a gate, more of a first come first serve kind of deal). In fact, there wasn't a display inside the security checkpoint area. It's a small terminal though, so it's easy to listen for any calls for your flight.
Touching down in Lima, I quickly made my way outside, where a taxi driver from Barranco's Backpackers was waiting for me. For $19 and after a 40 minute drive through Lima, I found myself in front of a green gated home.
