Terminal B
Ezeiza’s single departures building, 27,000 m². The airport’s own site never mentions a second one for check-in: the valet stand, the Multinivel E2 car park and the Google Maps pin for “Terminal de Partidas - Check In” all point here.
Since a 9-December-2024 resolution from ORSNA, Argentina’s airport regulator, airlines can use Terminal B’s check-in counters flexibly, assigned to match each carrier’s actual demand instead of a fixed counter per airline.
