JetSMART Baggage Guide: Avoid Extra Charges in 2026 

JetSMART is an ultra-low-cost carrier operating across South America. Its base fare includes only one personal item (45 x 35 x 25 cm, up to 10 kg). Carry-on bags and checked luggage cost extra from $7.50 USD for domestic Peru flights with prices rising significantly if purchased at the airport gate.

JetSMART has quietly become one of South America’s most booked budget airlines, connecting cities across Chile, Argentina, Peru, Colombia, Brazil, Uruguay, and Paraguay. Its ultra-low-cost model is straightforward: pay a low base fare, then add only what you need.

Baggage is where most travelers get caught off guard. Unlike traditional carriers that bundle bags into the ticket price, JetSMART charges for almost everything above a small personal item. The difference between buying your bag online at booking versus at the boarding gate can be more than 4x the original price on some routes.

What Does JetSMART’s Base Fare Actually Include?

JetSMART’s entry-level “Vuela SMART” fare includes exactly one personal item per passenger nothing more. That personal item must fit under the seat in front of you, not in the overhead bin. No carry-on bag, no checked bag. Both cost extra.

The airline also allows a few free additions alongside your personal item:

• A jacket or coat
• A small, closed umbrella
• A small camera
• Reading material (books, magazines, tablet)
• A small duty-free bag compliant with airport security rules
• Crutches, walkers, or approved mobility aids

If you’re traveling with an infant, a diaper bag up to personal item dimensions is permitted in addition to your adult allowance.

What Is the JetSMART Carry-On Baggage Allowance?

JetSMART’s carry-on allowance (the overhead bin bag) is a paid optional on its base fare. Once purchased, the carry-on must not exceed 55 x 35 x 25 cm and 10 kg, including wheels, handles, and pockets. One carry-on per passenger is the maximum allowed.

What Is the JetSMART Carry-On Size in Inches?

JetSMART’s carry-on dimensions convert to 21.7″ x 13.8″ x 9.8″ (length x width x height). This is slightly larger than what some ultra-low-cost carriers allow, making it compatible with most standard cabin bags. The personal item (under-seat bag) is smaller at 45 x 35 x 25 cm, or 17.7″ x 13.8″ x 9.8″.

How Much Is a Carry-On on JetSMART?

JetSMART carry-on fees vary by country and critically by when you purchase. Buying your carry-on at the boarding gate is always the most expensive option, sometimes three to four times the online rate. Below are the official fees from JetSMART’s optionals page:

The takeaway: Always purchase your carry-on at the time of booking. A Peru domestic carry-on that costs $7.50 USD online jumps to $25 USD at the counter a 233% price increase.

How Much Does a Checked Bag Cost on JetSMART?

A standard checked bag on JetSMART starts from $8 USD on Peru domestic routes when purchased at booking, rising to $32 USD at the boarding gate on the same route. For international flights, the price starts at $27.50 USD online and reaches $65 USD at the gate.

Each checked bag must weigh up to 23 kg and not exceed 158 linear centimeters (height + width + length). You may check up to 5 bags per passenger.

Overweight fees: If your checked bag falls between 23 kg and 32 kg, JetSMART charges a flat excess fee from $30 USD for Peru routes and from $35 USD on international routes, payable only at the airport counter. No bag over 32 kg is accepted under any circumstances.

What Is the JetSMART Baggage Allowance for Peru Flights?

On JetSMART Peru domestic routes, the airline uses a Weight Concept system rather than a piece-based system. This means your checked allowance is measured by total weight, not by number of bags. For example, if you purchase a 23 kg allowance, you could split that between two bags as long as each fits within the 158 linear cm size limit.

Key Peru-specific numbers:

• Carry-on: From S/ 50 online (approx. $13–14 USD), over S/ 120 at the airport
• Checked baggage: From $8 USD online; from $25 USD at the airport counter
• Overweight fee: S/ 65 per extra kilogram (one of the highest per-kg rates in Peru)
• Carry-on weight limit: 10 kg one of the most generous among Peruvian domestic carriers

For context, competing carrier Sky Airline Peru charges S/ 60 per extra kilo and LATAM charges between S/ 60 and S/ 120 per excess event. JetSMART’s per-kg rate of S/ 65 is slightly above Sky but comparable to LATAM’s upper range.

Is JetSMART Strict with Baggage?

Yes JetSMART is consistently strict about baggage compliance. Gate agents actively check carry-on sizes before boarding, and bags that exceed the allowance are pulled at the gate and charged the highest applicable fee. For international routes, that’s from $65 USD per bag. For Peru domestic routes, from $25 USD.

What this means in practice:

• A standard 20-inch rolling carry-on will typically pass the 55 x 35 x 25 cm size check
• Stuffed or overpacked bags that push the 10 kg limit get weighed at the gate
• Passengers who board with an unpurchased carry-on and a too-large personal item will be charged for both violations
• Only online check-in is free checking in at the airport counter costs from $3–10 USD depending on the route

Edge case: On some flights, for operational reasons, purchased carry-ons may be moved to the aircraft hold at no extra charge. This is done by the airline, not as a penalty, and does not affect your fee.

What Are JetSMART’s Rules for Special Baggage?

Competitors rarely cover special baggage in detail. Here’s what JetSMART actually allows:

Oversized baggage (e.g., surfboards, sports gear, bicycles):

• Weight limit: 23 kg
• Dimensions: between 158 cm and 230 cm linear
• Surfboards: up to 300 cm linear
• Maximum 3 oversized items per passenger
• Properly packed guitars and bass guitars may be classified as oversized baggage
• Fees start from $18 USD for Peru routes and $37.50 USD for international routes at time of purchase

Musical instruments:

• Small instruments may qualify as personal item or carry-on if they fit within dimensions
• Guitars and bass guitars must be checked as oversized baggage they are not permitted as carry-ons
• Always confirm with JetSMART before travel if your instrument is borderline in size

Medical devices:

• Battery-powered mobility aids (wheelchairs, scooters) require advance notification
• Manual wheelchairs are transported free of charge and do not count as baggage
• Lithium-ion batteries for personal devices (power banks, laptops) must travel in carry-on, never in the checked hold
• Spare lithium batteries are prohibited from checked baggage per international aviation safety rules

Pets:

• Dogs and cats only (no breed restrictions, no cargo hold)
• Carrier: soft-sided, max 38 x 35 x 22 cm, waterproof and ventilated
• Max total weight (pet + carrier): 10 kg
• Fee from $30 USD (Peru, at booking) to $100 USD (international, after purchase)
• Maximum of 4 pets per flight; must be booked by phone, not online

Is JetSMART a Good Airline?

JetSMART delivers exactly what it promises: low base fares across South America with a transparent add-on pricing model. Backed by Indigo Partners the same group behind Wizz Air, Frontier Airlines, and Volaris JetSMART operates with a consistent ultra-low-cost framework that works well if you understand the rules.

JetSMART is a good fit if:

• You’re traveling light with just a personal item
• You book all extras (bags, seats) at the time of purchase to lock in the lowest rates
• You check in online in advance (free, opens 72 hours before departure)
• You’re flexible and prioritize price over amenities

JetSMART is a poor fit if:

• You regularly travel with checked luggage and book close to departure
• You expect bundled meals, entertainment, or flexible cancellation by default

The airline does not offer free meals on any route. There are no loyalty miles. Cancellation on the basic fare is non-refundable. However, the FlexiSMART add-on allows date and time changes without a penalty fee (fare differences still apply), and the SMARTicket option on international routes allows full cancellation within 48 hours of purchase if the flight is 20+ days away.

How Early Should I Arrive for a JetSMART Flight?

JetSMART recommends completing online check-in between 72 hours and 70 minutes before departure. Arriving at the airport with a printed or digital boarding pass saves both time and money. Checking in at the airport counter costs from $3 USD (Peru domestic, at booking) to $10 USD (at the counter on the day of travel).

For planning purposes:

• Domestic flights: Arrive at least 90 minutes before departure
• International flights: Arrive at least 2.5 to 3 hours before departure
• With checked baggage: Add 20–30 minutes for bag drop

Boarding gates close early. Missing the gate closure even if you’re in the terminal means your carry-on gets charged at the highest gate rate, and you risk being denied boarding.

5 Tips for Avoiding Extra Fees on JetSMART

1. Buy all extras at initial booking. Carry-on bags, checked luggage, and seat selection are always cheapest when added during the ticket purchase not after.
2. Check in online. JetSMART charges for airport check-in. Doing it online is free and takes two minutes.
3. Weigh your bag before leaving home. JetSMART’s overweight flat fee kicks in the moment your bag exceeds 23 kg. A small luggage scale costs less than a single overweight charge.
4. Use the Weight Concept on Peru routes. You can distribute 23 kg across multiple bags on domestic Peru flights useful if you’re traveling with bulky but light items.
5. Pack lithium batteries in carry-on. Power banks and laptop batteries cannot go in the hold. If security catches them in checked luggage, your bag is opened, the battery removed, and you may face delays.
