Where are Peru's airports?
Peru’s main international airport is the Jorge Chávez International Airport (LIM), which is located in Lima. This airport recieves international flights from around the world, and is the airport that most travelers will fly into and out of when visiting Peru.
It's best to book flights in advance, especially during the high season. Flights are typically most expensive during Christmas/New Year's, Easter, and Fiestas Patrias (a holiday during the last weekend in July)
