Aerolíneas Argentinas Baggage Policy 2026: Fees, Weights & Allowances

Flying into Buenos Aires or heading down to Patagonia? Navigating the baggage rules for Argentina’s flag carrier can be tricky. 

The rules for a flight from Miami to Buenos Aires are completely different from a domestic hop to Iguazú Falls.

Whether you are carrying trekking poles for El Chaltén or wine from Mendoza, this guide covers everything you need to know about the Aerolíneas Argentinas baggage policy in 2026.

At A Glance: Baggage Allowance Cheat Sheet

Before you pack, check this summary. Aerolíneas Argentinas applies two different systems: the Weight Concept (Domestic) and the Piece Concept (International).

Baggage Type	Domestic Flights (Within Argentina)	Regional & International Flights	Max Dimensions
Personal Item	1 Included (All Fares)	1 Included (All Fares)	Fits under seat
Carry-On	1 Bag up to 8 kg (17 lbs)*	1 Bag up to 10 kg (22 lbs)	55 x 35 x 25 cm
Checked Bag	15 kg (33 lbs) usually included**	23 kg (50 lbs) usually included	158 linear cm

Note: “Promo” class domestic fares often exclude the standard carry-on. Check your ticket specific class.
Promo and Base fares may not include checked bags. Plus and Flex fares typically include one.

Carry-On Baggage Rules

The rules for what you can bring into the cabin depend heavily on your route and fare class.

The Personal Item

Every passenger, regardless of fare, is allowed one personal item free of charge.

• Weight Limit: Up to 3 kg (6.6 lbs).
• Examples: A purse, laptop bag, small backpack, or baby bag.
• Placement: Must fit under the seat in front of you.

The Standard Carry-On

Here is where travelers often get caught out. The weight limit changes based on your destination:

• Domestic Flights: Max weight is 8 kg (17 lbs).
• International/Regional: Max weight is 10 kg (22 lbs).
• Size Limit: 55 x 35 x 25 cm (including wheels, handles, and pockets).

 The “Promo Fare” Warning

If you booked the cheapest possible ticket (Promo Fare) for a domestic flight within Argentina, you may not be entitled to a carry-on bag in the overhead bin, only a personal item. 

If you bring a carry-on to the gate, you may be forced to check it and pay a fee. Always check if your ticket says “Includes Carry-On” or just “Personal Item.”

Checked Baggage Policy

Domestic Flights (The Weight Concept)

For flights within Argentina (e.g., Buenos Aires to Bariloche), the airline uses a “Weight Concept.”

• Standard Allowance: 15 kg (33 lbs) for Economy (Plus/Flex).
• Premium Economy: 2 pieces, typically up to 23 kg.
• Promo/Base Fares: Usually 0kg included. You must purchase baggage separately.

International Flights (The Piece Concept)

For flights to the USA, Europe, or wider South America, the “Piece Concept” applies.

• Economy: 1 piece up to 23 kg (50 lbs).
• Business (Club Cóndor): 2 or 3 pieces up to 23 kg (depending on route).
• Dimensions: The sum of width + height + length must not exceed 158 cm.

Baggage Fees & Excess Charges

If your bag is heavier than the allowance or if you need to add an extra suitcase, fees apply.

Buying Extra Bags

It is always cheaper to purchase additional baggage online up to 4 hours before your flight. Paying at the airport can cost up to 50% more.

• Domestic Extra Bag: Prices vary by route but expect to pay roughly $15-$30 USD equivalent (paid in ARS).
• International Extra Bag: $60 – $100 USD depending on the destination (USA/Europe routes are more expensive).

Overweight & Oversize Fees

• Overweight (Domestic): If your bag exceeds 15 kg but is under 23 kg, you pay a fixed excess fee.
• Overweight (International): Bags over 23 kg (up to 32 kg) incur a heavy fee, often around $100 USD.
• Hard Limit: No bag can weigh more than 32 kg (70 lbs) due to health and safety regulations for handlers. It must be sent as cargo if it exceeds this.

Special Baggage: Sports & Instruments

Heading to the Andes for skiing or bringing a guitar? Aerolíneas Argentinas has specific rules for “Special Baggage.”

Sports Equipment

Skis, snowboards, golf clubs, and surfboards (under 300cm) are considered special baggage. They are not usually included in your standard allowance and incur a fixed fee per leg.

• Domestic Fee: Approx. ARS 34,000 (rates subject to inflation change).
• Regional/Intl Fee: $60 – $150 USD depending on the route.

Musical Instruments

• Small Instruments: Can be carried on board if they fit in the overhead bin (replaces your carry-on) and do not exceed 80cm in length.
• Large Instruments: Must be checked as special baggage (fee applies) or you must purchase an extra seat for them (e.g., Cello).

4 Tips to Avoid Fees

1. Check Your Fare Class: “Promo” fares save money upfront but can cost more if you need to add bags later.
2. Weigh Bags Before Leaving: Domestic carry-on limits (8kg) are stricter than US/EU standards. Agents at Jorge Newbery (AEP) and Ezeiza (EZE) often weigh carry-ons.
3. Pre-pay Online: Never wait until the airport counter to add a bag. Use the “My Booking” section on the website or WhatsApp channel.
4. Join Aerolíneas Plus: Elite members (Gold/Platinum) often get free extra baggage allowance.

Common Questions

Is the 158cm linear dimension strict?

Yes. Linear dimension is Length + Width + Height. If your bag looks visibly oversized (e.g., a massive trunk), they will measure it. Standard large suitcases generally fit this rule.

Can I pool my baggage allowance with my family?

Generally, yes. If you are on the same reservation, agents often allow you to pool the total weight (e.g., two people with 15kg each can bring one 28kg bag), but this is at the agent’s discretion.

Can I bring a stroller for my baby?

Yes. One stroller, walker, or folding buggy can be transported free of charge in the hold for infants.

Can I bring my Mate and Thermos in a carry-on?

Yes! This is Argentina, after all. You can bring your mate kit, but the thermos must be empty of water to pass through security.

What happens if I have a connection from International to Domestic?

Usually, the international allowance (23kg) is honored on the domestic leg if it is on a single ticket. If you booked separate tickets (e.g., Miami to BA, then a separate booking to Mendoza), the stricter domestic rule (15kg) applies to the second flight.

Final Thoughts

The key to a smooth trip with Aerolíneas Argentinas in 2026 is knowing your route. Remember: 8kg for domestic carry-on and 15kg for domestic checked bags.

Don’t get caught by the “Promo” fare restrictions. Always check your specific allowance in the “My Booking” section of the Aerolíneas website before you pack to ensure the most current fee structure.
