Six years ago, when I was leaving from Lima Jorge Chávez International Airport, there was airport fee of 30.25 USD. I had to pay this fee even If I already had the ticked (with Iberia, so normal, not a low-fare airline). Besides, the fee had to be paid in US dollars, not Peruvian soles.
Currently, would I still have to pay the airport fee? Or is it now included in ticket price? This was the only airport ever where I had to pay some extra fee, so I assume it's nowadays either already included in ticket price, or that's just the Peruvian regulations.
