About the Buenos Aires → Lima route
Buenos Aires to Lima is a mid-range South American hop — just under 3,700 kilometres and about three hours forty minutes in the air, which puts it firmly in the "long domestic flight" category rather than anything requiring a flat bed and a sleep mask. LATAM (LA) does the heavy lifting on this route, as you'd expect given they've built their network specifically around connecting the continent's major cities. The passenger mix skews business and VFR (visiting friends and relatives) more than pure tourism, which means midweek departures tend to fill up faster than you'd guess for a route this length.
Why travel from Buenos Aires to Lima?
Argentines have been going to Peru in serious numbers for years, and the reasons stack up fast. The food angle is obvious but genuinely earned — Lima has restaurants that people fly internationally just to eat at, and Miraflores alone could keep you occupied for a week without repeating a meal. Beyond that, Machu Picchu remains the anchor attraction that pulls people who've been putting it off for a decade. There's also a real business corridor here, particularly in mining, agriculture, and finance, which explains the suited-up crowd on Monday morning flights. And for the Argentine middle class with roots across the region, Lima is often a connection point for family spread across Peru's interior. It's a route with genuine utility on multiple levels.

Practical tips for AEP → LIM
Lima's Jorge Chávez airport (LIM) sits in Callao, not Lima proper — budget 45 minutes to an hour to reach Miraflores by taxi or app-based ride, longer if you arrive during peak hours. The airport taxi concession desks inside arrivals are overpriced; Uber works reliably and costs a fraction of the price. Peru uses soles, and Argentina uses pesos — don't bother converting at AEP. Lima's climate is oddly counterintuitive: the grey, drizzly months (June through October) are actually peak tourist season inland. If you're flying Flybondi or another low-cost carrier on this route, check baggage allowances before you pack — carry-on restrictions get enforced.
