One more note: If you're planning on spending midnight to 6 am in the Lima airport, don't count on getting much rest. The international terminal was very busy and noisy all night long. The in-transit lounge wasn't so nice, and was hot the night we spent. The back gates were more calm, but LanChile kept rousing us away. Check to see if buying a business class ticket will get you access to the VIP lounge.
