Terminal B

Check-in in Terminal B sits between A and C

Gate signs for Terminal B at Ezeiza sit physically between Terminal A and Terminal C, and most Aerolíneas Argentinas passengers get sent here for check-in. Lufthansa, Iberia, and Swiss flights are associated with B at the airport level, but desks often sit in the shared A–B check-in hall. Think of B as the central island of counters and processing, not a separate pier full of gates.

Check-in islands for Aerolíneas Argentinas and SkyTeam partners line up in this B zone, and multiple Google Maps reviews mention that swapping lines takes less than two minutes if you picked the wrong island. Monitors above each island show flight numbers and destinations to Europe, South America, and domestic points, so confirm your AR, Iberia, Lufthansa, or Swiss flight on the screen before you commit to a queue.

Once you pass security and passport control from the B area, the departure level merges into the broader A–B–C airside space, and walking between the adjoining sections is a fully indoor, flat walk of just a few minutes. A TripAdvisor poster timed the walk between the A and B departure zones at roughly five minutes at normal pace, which matches the “one big building” description you see in Spanish-language forums.

Lines for Aerolíneas Argentinas in the B check-in hall can be long, with multiple Google reviewers calling out 30–60 minute waits during Argentine holiday weekends in July and around Christmas. Local forum regulars recommend adding at least 30 extra minutes for AR check-in if you fly on a Friday evening or on long weekends, especially for widebody departures to destinations like Madrid or Miami.

Confusion about terminals shows up often in TripAdvisor threads, with some Aerolíneas passengers saying their booking showed Terminal B, but the airline had shifted desks to an island marked A or C on the day. In one case, a traveler reported walking back and forth across the shared A–B area for about 10 minutes before spotting their flight on the overhead monitors. Treat the printed terminal on your ticket as a hint, then follow the screens inside the building.

Terminal B itself has no clearly separate list of restaurants or branded shops; food and retail options live in the combined post-security concourse that covers A, B, and C. That means your closest coffee or snack might technically sit in the “A” or “C” segment even if you checked in at a B counter, and most travelers report just walking 3–5 minutes along the main spine until they see a place they recognize.

There is no dedicated Terminal B lounge catalogued for Lufthansa, Iberia, or Swiss, so premium passengers usually end up in partner lounges signed under the A or C sections, depending on daily operational assignments. Lounge eligibility still follows alliance and ticket rules, but you may have to walk 5–10 minutes from a B check-in desk to reach the correct lounge, then back toward your eventual gate.

Regular EZE flyers on FlyerTalk mention that Aerolíneas Argentinas has shifted between Terminals A, B, and C multiple times over recent years, including a noted change in 2018, so they always re-check the airport website or app within 24 hours of departure. They also call out that gate changes for long-haul flights to Europe can appear within the final hour before boarding, so keep an eye on monitors near your gate row.

Watch out for inconsistent terminal signage at curbside, as one TripAdvisor user described being dropped at a sign for B, only to learn from a staff member that their Aerolíneas desk had moved closer to the A side that morning. If you arrive by taxi or remis, ask the driver to stop near the central curb area between A and B, then walk inside and confirm the correct island by flight number on the overhead screens.

One practical tip: plan to arrive at least three hours before an international departure from the B check-in zone, and when you enter the building, go straight to the nearest monitor wall, find your flight by number, and then walk to the listed island or counter range before joining any line.
