Aerolineas Argentinas

Aerolineas Argentinas is the country's flag carrier, built around a Buenos Aires hub that feeds a wide domestic network and regional routes across South America. It is a full-service airline rather than a low-cost one, so most of its jets carry a small premium cabin up front alongside the main economy cabin.

The fleet is Boeing narrowbody at its core, with the Embraer E190 handling thinner regional routes. Which cabin you can book depends on the exact aircraft: most of the 737s pair a recliner business cabin with economy, one denser 737 fit swaps business for a small premium economy zone, and the E190 keeps a compact business cabin of its own.

The 737-800, 737-700 and 737 MAX 8 are the backbone of the network, each with a small two-by-two recliner business cabin at the nose and a long economy cabin behind it. Business here is a wider recliner seat rather than a lie-flat, which suits the short-to-medium sectors these jets fly.

One higher-density MAX 8 fit is configured differently: it drops the business cabin and instead offers a small premium economy zone at the front, with standard economy filling the rest. The Embraer E190 rounds out the fleet on regional routes, carrying its own compact business cabin ahead of economy. It pays to check which aircraft your flight uses, since the cabins on offer are not identical across the 737s.

Business on the 737s and the E190 is a recliner-style seat in a two-by-two layout, so you get more width, more recline and no middle seat to negotiate. It is a comfortable step up for the flight times involved rather than a long-haul flat bed, and the front position means a quick boarding and a fast exit.

Economy is a standard three-by-three cabin on the 737s and a two-by-two on the E190, where there is no true middle seat to avoid. The premium economy zone on the denser MAX 8 sits between the two: more space than a regular economy row without a separate business product. Across the fleet, the front of each cabin is the calmer, quicker option and the rear sits nearest the galleys.

If you want the most room, the recliner business cabin at the nose of the 737s is the clear pick, and the bulkhead row there gives the fastest exit. On the E190, the two-by-two economy layout is a quiet win in itself, since every seat is either a window or an aisle with no middle to draw.

In economy on the 737s, target a row over the wing for the steadiest ride and a forward row for quick boarding and a short walk off the aircraft. The exit rows carry extra legroom where the layout allows it. Avoid the last few rows near the rear galley and toilets, which get the most noise and movement. On the premium-economy MAX 8, the front zone is worth the difference if legroom is your priority.
