Samuel:
Make sure you don't delay too long in booking your flights and purchasing your tickets for the Taca-Peru and SAETA (Aces) segments. You need to have them booked before Taca-Peru begins international service and before SAETA starts up its LIM-UIO service. At least the SAETA service from UIO-LIM was rumored to start sometime in May. Therefore, right before you book your flights, confirm with both SAETA and TACA-Peru that they haven't started service on these routes, or you could be one unhappy camper when you get back home.
Happy Travels!
