LATAM Seat Selection: Extra-Legroom Seats, Fees and Sitting Together

Extra-legroom seats are seating within Economy, not a separate premium cabin. If you see 'XL' or 'extra legroom', check the description for that particular seat rather than rely on the label.

For LATAM fares, Premium Business and South American connections, see our LATAM Airlines flights guide.

On trips that combine LATAM with other airlines, LATAM says seats can only be bought at the airport. Flights operated by a partner follow that airline's seat rules.

If you don't choose a seat, you can still fly: LATAM assigns one, and passengers without a seat number get one at the airport on the day of travel.

LATAM says that when you travel with a child under 12, it assigns seats next to at least one adult companion without the need to buy seats in advance. You can check the assignments on the boarding pass from 48 hours before the flight. That isn't a promise that the whole family will be in one row, or in the seats you would prefer.

• Keep everyone on the same booking.
• Check seat assignments as soon as they're available.
• Contact LATAM if a child is separated from the accompanying adult.
• Couples shouldn't assume free seats will be together. If sitting side by side matters, compare paying for seats with a fare that includes seat selection.

On Sydney or Melbourne to Santiago, or a long flight from the US to São Paulo, choose around how you travel. An aisle is useful if you get up often; a window suits someone who wants to settle in. For couples, two aisles across from each other can work well if neither wants a middle seat.

Layouts differ between aircraft, so there isn't one favourite row for every flight. Check the seat map for your exact flight, and look away from toilets and galleys if rest matters.

LATAM says it refunds purchased seats when your fare conditions allow it. The conditions are on your purchase receipt or under 'What your fare includes' in My Trips.

• If your flight is rescheduled and you can't find seats with the same characteristics, you can request a refund.
• The same applies when a flight is moved earlier or delayed within the same travel day.
• If LATAM changes your seat for operational or safety reasons and can't offer one with the same or better conditions, you can request a seat refund through LATAM's chat.

What are LATAM+ and XL seats, and are they worth it?

LATAM+ is seating within Economy, not a separate premium cabin. If you see 'XL' or 'extra legroom', check the description for that particular seat rather than rely on the label.

We'd consider paying if you're tall or find the knee room in standard Economy uncomfortable, particularly on a long flight. On a short connection, we'd be more selective about the price.

Extra legroom doesn't automatically mean a wider seat, more recline or a blocked middle seat. We check the seat map, proximity to toilets, and any fixed armrests or storage restrictions. For an exit row, you must meet the safety requirements. And before paying, we check whether your fare or status already includes the seat.

Which Economy seat would you choose on a long flight?

We choose around how you travel. An aisle is useful if you get up often; a window suits someone who wants to settle in and lean against the side. For couples, two aisles across from each other can work well if neither wants a middle seat.

We look away from toilets and galleys if rest matters, and check recline before choosing the last row of a section. On these routes, we wouldn't give you a favourite row without checking the exact aircraft and seat map; layouts can differ between flights.

If you're connecting onwards after Santiago or São Paulo, we prioritise a comfortable connection over paying to sit near the front just to get off sooner.

• Fare and status checked for included seat selection
• Seat description read, not just the 'XL' or 'extra legroom' label
• Exit-row eligibility confirmed for every passenger in that row
• Family on one booking, with assignments checked once available
• Seat map checked for the exact aircraft on long flights
• Partner-operated flights checked for that airline's seat rules
