LATAM Airlines A320

It is a fare rather than a separate cabin: the front economy rows with the middle seat left free and a slightly better service. You get more room and a quieter boarding, but the seat itself is standard economy geometry, so it suits travellers who want space without expecting a recliner.

The extra-legroom rows around the over-wing exits give the most stretch room, and the seat map shows exactly where they fall. A window or aisle position avoids the middle of the three-across block, and the front of the cabin boards and clears faster than the rear.

The last rows ahead of the rear galley and lavatory carry the most noise and queue traffic, so they are best avoided. Middle seats with no window or aisle are the least comfortable in economy on a busy flight.

On the longer sectors, yes: the extra legroom pays off over three or four hours in the seat, and the pair sit far enough from the galleys to stay quiet. The trade is that a bulkhead-style exit row sometimes has a fixed armrest and no seat pocket at your feet, so if you like to spread out with a book and a bag, weigh that against the legroom.

Fit varies by sub-fleet, so this is one to check on the published layout or at booking. LATAM has been refreshing its single-aisle cabins, and streaming to your own device is the more reliable bet than a seat-back screen on these domestic jets. Bring a charged phone and a small battery pack if power matters to you.
