JetSMART Baggage Rules, Carry-On Sizes, and Bag Fees
JetSMART operates as an ultra-low-cost carrier across Chile and South America. Base tickets include only a compact under-seat bag, while larger cabin luggage and checked bags require an additional fee or a fare bundle upgrade. Because baggage fees follow dynamic pricing, your route, departure date, and purchase timing determine your total baggage cost.
Standard JetSMART tickets include one free personal item measuring up to 45 x 35 x 25 cm (up to 10 kg) that must fit under the forward seat. Overhead carry-on bags (up to 10 kg) and checked bags (up to 23 kg) require paid add-ons or bundle upgrades. Ancillary fees increase significantly when bags are purchased at airport check-in counters or boarding gates.
Baggage Allowance Snapshot
Every JetSMART ticket includes a single under-seat personal item. All overhead carry-on bags and checked luggage require an extra fee or a bundled fare.
What can change: Dynamic fees vary by route (domestic Chile vs. international South America), seasonal demand, fare bundle tier, and purchase channel.

Official Source Verification
Baggage rules can vary by fare, cabin, route, operating carrier, traveler status, and purchase channel. BaggageBase separates published rules from practical guidance.
How BaggageBase Checks This Information
BaggageBase monitors official airline channels, published conditions of carriage, customer support disclosures, and passenger contracts. Because JetSMART operates as an ultra-low-cost carrier (ULCC), baseline baggage rules such as dimension limits and weight caps remain consistent across its fleet, while ancillary service prices fluctuate in real time. We review baggage policies against current booking interfaces to distinguish hard size thresholds from dynamic pricing rules.
Personal Item Rules (Bolso de Mano)
Every passenger on JetSMART is entitled to carry one personal item (bolso de mano) free of charge. This allowance applies to all ticket types, including promotional base fares such as "Vuela Ligero" or "Simple."
Personal Item Size and Weight Limits
The personal item must meet the following restrictions:
- Maximum Dimensions: 45 x 35 x 25 cm (17.7 x 13.8 x 9.8 in)
- Maximum Weight: 10 kg (22 lbs)
- Placement Requirement: Must fit completely beneath the seat directly in front of you.
Your personal item can be a compact backpack, a laptop case, a purse, or a small duffel bag. External accessories such as wheels, carry handles, and expanded side pockets count toward the total dimensions.
If you use a soft backpack, avoid overfilling it. A bag packed beyond capacity will bulge past the 25 cm depth limit and fail airport sizer checks. Review how these measurements fit regional and global airline requirements in our international carry-on size guide.
Overhead Carry-On Baggage Allowance (Equipaje de Mano)
Overhead carry-on luggage (equipaje de mano) is not included in JetSMART base fares. Travelers who wish to bring a standard cabin suitcase into the aircraft cabin must purchase it as an ancillary add-on or select a higher fare bundle that includes cabin luggage.
Carry-On Dimensions and Conditions
A paid overhead cabin bag must meet these specifications:
- Maximum Dimensions: 55 x 35 x 25 cm (21.6 x 13.8 x 9.8 in)
- Maximum Weight: 10 kg (22 lbs)
- Placement Location: Aircraft overhead storage bins.
The 55 x 35 x 25 cm limit includes wheels, handles, and side hardware. JetSMART limits overhead bin space, so purchasing your carry-on early ensures space is reserved for your itinerary.
| Item | Allowance | Size or fit rule | Important condition |
|---|---|---|---|
| Personal Item (Bolso de Mano) | 1 piece included free | 45 x 35 x 25 cm (17.7 x 13.8 x 9.8 in), max 10 kg | Must fit entirely under the seat in front |
| Overhead Carry-On (Equipaje de Mano) | 1 paid piece (or bundled) | 55 x 35 x 25 cm (21.6 x 13.8 x 9.8 in), max 10 kg | Wheels and handles included; placed in overhead bin |

Checked Baggage Policy and Allowance (Equipaje Facturado)
Checked bags (equipaje facturado or equipaje de bodega) travel in the aircraft cargo hold. Base fares do not include any checked luggage allowance.
Standard Checked Luggage Limits
When you buy a checked bag on JetSMART, the following parameters apply:
- Maximum Weight: 23 kg (50.7 lbs) per piece
- Maximum Linear Dimensions: 158 linear cm (62 linear inches), calculated as length + width + height.
- Piece Limit: Up to 5 checked bags per passenger.
Each checked bag is purchased as an independent item. Baggage fees are charged per passenger, per flight segment. If your journey involves connecting segments that are not booked as a through-ticket, baggage must be paid for each flight individually.
Baggage Fees by Purchase Channel and Dynamic Pricing
JetSMART uses dynamic pricing for all baggage ancillaries. The cost of a personal item upgrade, overhead carry-on, or checked bag is not a fixed universal amount. Instead, the fee varies depending on the specific flight route, booking window, season, and payment channel.
The Pricing Hierarchy
Baggage prices rise as departure approaches. The airline structures its fees into four clear stages:
- Initial Online Booking: Adding baggage while booking your flight through the official website or mobile app offers the lowest available price.
- Post-Booking ("Manage My Booking"): If you add bags online after completing your reservation or during web check-in, the fee increases moderately.
- Airport Check-In Counter: Purchasing baggage at the airport check-in desk before security incurs a significantly higher rate.
- Boarding Gate Interception: Unpaid overhead bags or oversized personal items intercepted at the boarding gate face the highest penalty tier.
| Purchase Channel / Timing | Pricing Tier | Route Scope | Recommendation |
|---|---|---|---|
| Initial Booking (Online/App) | Lowest available rate | Domestic Chile & International | Best value; purchase when buying tickets |
| Post-Booking (Web / Check-In) | Moderate price tier | Domestic Chile & International | Add online before heading to the airport |
| Airport Check-In Desk | High price tier | Domestic Chile & International | Pay at desk if your bags exceed online caps |
| Boarding Gate | Highest penalty rate | Domestic Chile & International | Avoid by verifying bag size before security |
Domestic flights within Chile are priced in Chilean Pesos (CLP), while international flights across South America are priced in US Dollars (USD) or local currencies. JetSMART airport desks operate on a cashless basis, requiring a credit or debit card for counter payments.

Overweight, Oversized, and Excess Baggage Rules
Checked bags that exceed standard weight or dimensional thresholds require extra payments at the airport.
Overweight Luggage (Sobrepeso)
A standard checked bag allows up to 23 kg (50.7 lbs). If your bag weighs between 23.1 kg and 32 kg (50.8 to 70.5 lbs), it is classified as overweight (sobrepeso).
- Overweight luggage incurs an excess fee charged either as a flat fee or as a per-kilogram penalty, depending on the route.
- Absolute Maximum Limit: 32 kg (70.5 lbs). Under aviation safety and ground-handling rules, bags exceeding 32 kg will not be accepted as passenger baggage.
Oversized Checked Bags
Checked bags exceeding 158 linear cm up to a maximum of 230 linear cm require oversized baggage processing under the special baggage (equipaje especial) category. Any piece exceeding 230 linear cm cannot fly as passenger luggage.
| Condition | Threshold | Additional fee | Acceptance limit |
|---|---|---|---|
| Standard Checked Bag | Up to 23 kg (50.7 lbs), max 158 cm | Standard checked bag fee | 23 kg |
| Heavy Baggage (Sobrepeso) | 23.1 kg to 32 kg (50.8 to 70.5 lbs) | Overweight fee per bag or kg | 32 kg hard stop |
| Oversized Baggage | 159 cm to 230 linear cm | Special baggage handling fee | 230 linear cm |
| Unacceptable Luggage | Over 32 kg (70.5 lbs) or over 230 cm | Not accepted | Must ship via cargo |
Fare Types, Loyalty Discounts, and Traveler Exceptions
JetSMART structures its ticket offerings around unbundled base fares and combined service bundles.
Fare Bundles
- Base Fares ("Simple" / "Vuela Ligero"): Includes only the single personal item (45 x 35 x 25 cm, max 10 kg). All other baggage requires separate purchases.
- Pack SMART: Typically bundles one personal item, one overhead carry-on bag (10 kg), standard seat selection, and priority boarding.
- Pack Full: Typically bundles one personal item, one overhead carry-on bag (10 kg), one 23 kg checked bag, premium seat selection, and priority boarding.
Purchasing a bundle is often more economical than buying an overhead bag, checked bag, and seat selection separately.
Club SMART Loyalty Program
Members of Club SMART receive discounted fares on select routes. Active members may also access promotional rates on ancillary baggage add-ons when booked through their member profile. These discounts apply only to purchases completed online prior to departure.
| Eligible traveler | Free allowance | Weight/size cap | Conditions |
|---|---|---|---|
| Standard Passenger (Base Fare) | 1 personal item | 45 x 35 x 25 cm, max 10 kg | Fits beneath the seat in front |
| Pack SMART Passenger | 1 personal item + 1 carry-on | 10 kg each | Carry-on fits in overhead bin |
| Pack Full Passenger | 1 personal item + 1 carry-on + 1 checked bag | Cabin 10 kg each; hold bag 23 kg | Checked bag max 158 linear cm |
| Lap Infant (Under 2 years) | 1 stroller, car seat, or bassinet | Standard infant equipment specs | Checked into cargo hold free |
| Passenger with Disability | Certified mobility equipment | Meets safety regulations | Transported free in hold |
Infants and Children
Infants under two years of age traveling on an adult's lap do not receive an individual cabin baggage or personal item allowance. However, JetSMART allows one fully collapsible stroller, car seat, or baby carrier to be checked into the cargo hold free of charge per traveling infant.
Mobility and Medical Equipment
Passengers requiring wheelchairs, walkers, crutches, or prosthetic devices may transport these items free of charge. Wheelchairs with electric batteries must be declared to JetSMART customer service in advance to verify battery safety protocols before airport arrival.
Special Baggage: Sports Equipment and Musical Instruments
Items that do not fit into standard suitcase dimensions can be checked under the Equipaje Especial (Special Baggage) policy.
Categories Covered
- Sports Equipment: Bicycles, surfboards, golf clubs, snowboards, skis, and diving gear.
- Musical Instruments: Guitars, cellos, keyboards, and brass instruments.
Rules and Fees for Special Items
- Maximum Size: Up to 230 linear cm.
- Maximum Weight: Up to 23 kg standard, or up to 32 kg with the applicable overweight fee.
- Fees: Special baggage is subject to dedicated rates that vary by route and booking window. Paying online in advance is significantly cheaper than paying at the airport counter.
- Packing Requirements: Bicycles must have handlebars turned sideways, pedals removed, tires partially deflated, and be packed in a rigid box or dedicated travel case. Instruments and fragile gear must be secured inside rigid, hard-sided travel cases. Soft bags may require a signed limited-liability release at check-in.
Gate Enforcement and Penalty Procedures
JetSMART strictly monitors carry-on baggage at airport boarding gates, especially at major hubs such as Santiago (SCL), Antofagasta (ANF), and Concepción (CCP).
Boarding Gate Sizer Checks
Gate agents routinely ask passengers on base fares to insert their personal items into metal sizing boxes (45 x 35 x 25 cm).
- Fit Check: The bag must slide into the sizer freely without forceful shoving.
- Overhead Verification: Boarding passes display whether overhead carry-on luggage was purchased. Passengers carrying rolling suitcases or large duffels without paid cabin allowances are flagged immediately.
Gate Penalties
If your bag does not fit the personal item sizer, or if you bring an unpaid cabin suitcase to the boarding gate, you will be charged the airport gate baggage fee.
Once the penalty fee is paid by debit or credit card, the airline will either allow the bag in the overhead bins (subject to available space) or tag the bag and send it directly to the cargo hold. Passengers who refuse payment will be denied boarding.
JetSMART Airport Baggage Checklist
Follow these steps before heading to the terminal to avoid unexpected baggage penalties.
- Measure including outer hardware. Confirm that your personal item is under 45 x 35 x 25 cm and your carry-on is under 55 x 35 x 25 cm, measuring from the bottom of the wheels to the top of the handle.
- Weigh your bags at home. Ensure your cabin items do not exceed 10 kg and your checked suitcase remains under 23 kg to prevent steep overweight charges.
- Add baggage during your initial booking. Online rates are always cheaper than airport prices. Do not wait to buy luggage at the airport counter or boarding gate.
- Use a soft, compressible backpack as a personal item. Rigid bags that bulge can fail the gate sizer box test, while soft backpacks compress into tight measurement frames.
- Keep essential medication and electronics in your personal item. If overhead cabin space fills up and your carry-on bag must be checked, your critical valuables stay with you.
- Have a cashless payment method ready. JetSMART airport desks and gate counters generally do not accept cash for baggage fees or overweight charges.

Final Booking and Travel Considerations
When flying with JetSMART, remember that your ticket follows an ultra-low-cost model. Your base fare covers only your seat and a single under-seat personal item measuring up to 45 x 35 x 25 cm.
To keep travel expenses minimal, measure your bags before packing, weigh them accurately, and purchase any needed carry-on or checked baggage during your initial ticket purchase. Arriving at the gate with unpaid or oversized bags will lead to the highest fee tier.
Airline baggage rules and fees can change by route, fare, cabin, operating carrier, traveler status, purchase channel, and departure date. Check the airline's official baggage policy or calculator before booking, paying, or traveling. BaggageBase reviews information for 2026 where possible, but the airline's published terms remain the final authority.
