LATAM Airlines Carry On Size

LATAM Airlines measures its cabin bag in centimeters only: 55 x 35 x 25 cm, wheels and handle included. Economy gets a 12 kg cap. That LATAM Airlines carry-on size box is smaller in every dimension than the familiar US 22 x 14 x 9 inch standard.

Converted, the LATAM Airlines carry-on size limit works out to roughly 21.7 x 13.8 x 9.8 inches. US travelers used to a 22 inch bag going unchecked will notice the gap. LATAM also publishes a weight cap and expects you to meet it.

Check your bag with a size checker before you leave for the airport. Not at the gate.

The carry-on box: dimensions and weight

LATAM states the limit as 55 cm high, 35 cm long and 25 cm wide. Wheels and handle count toward that, per its own baggage dimensions and weight page. LATAM publishes no inch figure of its own, so every inch conversion here comes from that cm number.

Weight is capped at 12 kg (26 lb) in Economy. Premium Economy and Premium Business get a higher 16 kg (35 lb) cap for the same size box.

That weight cap is the detail travelers moving from a US carrier miss most. Delta and American rarely weigh a carry-on at the gate. LATAM’s own published kg limit says it is prepared to.

How strict the sizer is, honestly

LATAM Airlines carry-on size enforcement varies by airport. LATAM publishes no station by station pattern for how often staff weigh or measure a cabin bag, so no such claim appears below.

What is verifiable is simpler. LATAM has published both a size and a weight number. A bag close to either limit is a real risk, not a theoretical one.

Bring a bag built for the box. Do not bring one you are hoping clears it.

Which fares include a full carry-on

LATAM’s fare ladder decides whether you get a cabin bag at all. This is where most surprises happen.

On a Basic fare, only the personal item is included. There is no carry-on and no checked bag in the price.

Step up to Light and the carry-on is included, though a checked bag still costs extra. Plus and Top fares add one or two included checked bags on top of the same cabin allowance.

LATAM Pass Platinum and higher elite members on a Light fare or above get one extra checked bag free. That applies on LATAM operated flights and is easy to miss on the fare page alone.

The personal item and what happens if a bag fails

The personal item box is 45 x 35 x 20 cm, about 17.8 x 13.8 x 7.9 inches. It is capped at 10 kg (22 lb) and it rides on every fare, including Basic.

This is the one bag a Basic fare passenger always gets. Pack accordingly if you booked the cheapest ticket.

When a bag fails the sizer or the scale, expect the gate agent to send it to the hold. See the site’s LATAM Airlines baggage fees page for the checked bag pricing that applies once that happens.

Bags that fit the LATAM box

A US style 21 or 22 inch spinner is often too tall for LATAM’s 55 cm limit once wheels and handle are counted. The Travelpro Maxlite 5 21 inch softside spinner measures 23 x 14.5 x 9 inches overall by the maker’s own published spec, about 58.4 cm tall.

That clears LATAM’s 55 cm ceiling by nothing. It is over before you even account for a bag packed full and rounded out.

Bags built for the tighter international size class fare better. The Delsey Paris Helium Aero 19 inch international carry-on is sized for European and Asian style boxes rather than the US 22 inch standard.

That puts it closer to LATAM’s limit on paper. Still measure your own unit with wheels and handle before relying on it.

The Kenneth Cole Reaction Out of Bounds 20 inch hardside runs about an inch shorter than most 20 inch carry-ons. That extra inch of margin is exactly what a strict box like LATAM’s rewards.

Whichever bag you bring, a tape measure with a self lock settles the question at home instead of at the counter.

If you already own a US standard 22 inch bag, weigh and measure it at home with the same tape measure. See how far over it runs.

A snug fit at home often becomes a failed fit once a bag is stuffed for a two week trip. Leave margin rather than packing to the exact centimeter.

The bottom line

LATAM Airlines carry-on size comes down to 55 x 35 x 25 cm and 12 kg in Economy. Both are smaller than what many US travelers are used to carrying free.

Book at least a Light fare for a cabin bag to be included at all. Measure your bag with wheels and handle attached, and weigh it before you leave the house.

A bag built for the international size class, not the US 22 inch standard, is the safer bet on LATAM. Use the site’s size checker and learn to measure carry-on luggage correctly the first time.
