I don't think there is one (at least based on what the check-in agent told me). I didn't really look for one as I spent the time in the City and browsing the few stores.

I found Lima airport very good and LAN service definitely above par. CUZ is a much smaller airport but even there, the facilities are new, clean and above par.

One interesting note: During the last 30 minutes of descent into CUZ, the cabin pressure is manipulated so that we got used to the higher altitude.
