Last-minute pesos usually get swapped at the Banco Nación branch
This Banco Nación sits landside at Aeroparque Jorge Newbery (AEP), before security, so you can stop here even if you’re just dropping someone off. It’s a standard bank branch, not a kiosk, and it mainly serves travelers who want to deal with cash before heading to the check-in counters.
Most flyers mention this spot as the place to exchange leftover Argentine pesos before flying out of Buenos Aires. Because it’s before security, you can use it regardless of airline or destination, and you don’t need a boarding pass to walk in. It’s one of the few options in the airport tied to an official national bank rather than a third-party currency booth.
The branch is listed with a middle-of-the-road rating of 3 out of 5, so manage expectations on speed and service. You’re here for basic transactions: currency exchange, ATM withdrawals, and standard Banco Nación banking, not premium airport perks. Compared with city-center branches, lines here can be shorter outside peak morning and evening departure banks, but that still varies by day.
Because this location is landside and not in a specific terminal concourse, you’ll want to build in a 20–30 minute buffer before your airline’s check-in cutoff. That gives you time for a short queue, a quick exchange, and then the security line. If your priority is a good exchange rate, it’s still smarter to handle large conversions in the city; think of this branch as a cleanup stop for smaller leftover amounts.
Practical tip: Use the ATMs here to withdraw a last bit of cash or clear out small remaining pesos, then keep a few low-denomination notes handy for taxis or coffee once you land at your next airport.
