Carry-On Baggage Rules
LATAM distinguishes strictly between a “Personal Item” and a “Carry-On Bag.” Knowing the difference can save you gate-check fees.
The Personal Item (Free for Everyone)
Every passenger, regardless of fare class, allows one small personal item. This includes:
- A purse or laptop bag
- A small backpack
- A diaper bag
The Rule: It must fit under the seat in front of you. If it doesn’t, you will be forced to pay for it as a carry-on or checked bag.
The Carry-On Bag (Fare Dependent)
This is the bag that goes in the overhead bin.
- Dimensions: Max 55 cm x 35 cm x 25 cm (including wheels and handles).
- Weight: Generally 10 kg (22 lb) for Economy. Premium Economy and Business class passengers get 16 kg (35 lb).
Warning for Basic Fares: If you book the cheapest “Basic” or “Promo” fare, a carry-on bag is NOT included. You will only be allowed a personal item.
If you bring a carry-on to the gate, you will be charged a premium fee to check it.
Checked Baggage Policy
Your checked luggage allowance depends entirely on the bundle you purchased (Basic, Light, Standard, or Full) and your route.
Standard Allowance
- Weight: Max 23 kg (50 lb) per bag.
- Size: Max 158 linear cm (Height + Length + Width).
Route Specifics
- Domestic & Regional: Most “Light” fares have a $0 checked allowance. “Standard” fares usually include 1 bag.
- International: Long-haul economy usually includes 1 bag. Business Class typically includes 2 to 3 bags depending on the route.
- The Miami/Quito Exception: On flights between Quito-Miami and Guayaquil-New York, there is a strict limit due to operational capacity. Economy passengers are capped at 1 checked bag total, and Premium passengers at 2 bags.
Excess Baggage Fees
LATAM uses a dynamic pricing model based on when you purchase the bag.
- Purchase >48 Hours in Advance: Lowest price (up to 40% off).
- Purchase 48h – 6h Before Flight: Mid-tier price.
- Purchase <6h or at Airport: Highest price.
Pro Tip: Never pay for bags at the airport if you can avoid it. A bag that costs $30 online in advance can easily cost $60-$100 at the check-in counter.
Overweight and Oversized Fees
If your bag exceeds the standard limits, the fees stack up quickly.
- Overweight (23kg to 32kg): You will pay a fixed fee per bag.
- Overweight (32kg to 45kg): A higher fee applies. Note that for flights to/from Argentina, Europe, or Oceania, the absolute maximum weight per bag is 32 kg (you cannot pay for heavier; it must go as cargo).
- Oversize (>158 linear cm): A separate fee applies for dimensions, regardless of weight.
Note: You cannot combine weights. If you have two bags allowed at 23kg each, you cannot bring one bag weighing 30kg and one weighing 16kg without paying a fee.
Special Items & Exceptions
Sports Equipment & Musical Instruments
Items like surfboards, bikes, and guitars are considered “Special Baggage.”
- They may count as part of your checked allowance if they fit within standard dimensions (rare for surfboards/bikes).
- If they exceed dimensions (up to 300 linear cm), you must pay a Special Baggage Fee.
- Fees vary by route but generally range from $50 to $150 USD.
Infants and Children
- Infant on lap (under 2): You can check one stroller, car seat, or travel crib free of charge.
- Children (2+): Standard adult baggage rules apply.
Service Dogs
Emotional support dogs are no longer accepted on flights to/from the USA. Recognized service dogs travel for free but must be documented in advance.
5 Tips to Save on LATAM Baggage Fees
Check the “Basic” Fare Fine Print
The cheapest ticket often ends up being more expensive if you have to add a carry-on later. Compare the “Standard” fare price against the “Basic” fare + bag fees.
The 48-Hour Rule
Always add your bags via the “My Trips” section on the LATAM website at least 48 hours before departure for the best rate.
Leverage LATAM Pass
Elite members (Gold, Platinum, Black) get extra baggage allowances regardless of the fare class.
Use a Scale
LATAM agents can be strict. If your bag is 24kg, you will likely be charged. Weigh it at home.
Wear Your Heaviest Gear
If you are close to the weight limit, wear your heavy coat and boots onto the plane to free up kilograms in your suitcase.
Frequently Asked Questions
Can I pool my baggage weight with my travel companion?
No. LATAM does not allow weight pooling. Each bag must individually meet the 23kg requirement.
What happens if I have a connecting flight with another airline?
If your itinerary includes a partner airline (like Delta or Iberia), the baggage rules of the “Most Significant Carrier” usually apply.
However, if you booked separate tickets, you will need to claim and re-check bags according to each airline’s rules.
Can I pay for bags with cash at the airport?
While possible at some hubs, many airports are moving cashless. It is safer and cheaper to pay online using a credit card.
Does LATAM allow “Smart Bags”?
Yes, but only if the lithium battery is removable. If you cannot remove the battery, the bag will not be allowed in the hold or cabin.
Final Thoughts
By measuring your bags at home and paying for any extras at least 48 hours before you fly, you can save significantly.
Always log in to the “My Trips” portal on the LATAM website to see the specific allowances for your route, as seasonal restrictions can change.
