JetSMART Baggage Rules 2026

The carry-on limit is 55 x 35 x 25 cm and 10 kg, and JetSMART measures it with wheels, handles and pockets included. It is a paid extra on the SMART fare, limited to one per passenger, and it goes in the overhead bin. On some flights JetSMART moves carry-ons to the hold for operational reasons at no extra charge.

Every fare includes one small bag or backpack up to 45 x 35 x 25 cm and 10 kg, again counting wheels, handles and pockets. A purse or small backpack qualifies. It must fit under the seat in front of you, and that rule changes in the first row and at emergency exits, where nothing can stay at your feet.

Infants without a paid seat also get their own small hand bag, as long as it meets the same size limit.

Yes, 10 kg is the published cap for both the free small bag and the paid carry-on. Size and weight limits apply together, so a bag inside 55 x 35 x 25 cm can still be refused in the cabin if it is heavier than 10 kg.

Only the two Flexi packs do; SMART comes with a small bag alone. SMART covers the fare, the 45 x 35 x 25 cm bag and AAdvantage miles. FlexiSMART adds a carry-on, a checked bag, priority boarding and a seat in rows 15 to 32, shown in the Chilean FAQ at + CLP 34,200. FlexiSMART+ adds a first-row seat and a printed boarding pass for + CLP 51,400. JetSMART says pack prices depend on the fare you pick.

SMART earns American Airlines AAdvantage miles even though it includes no carry-on.

On Chilean domestic flights a checked bag starts at CLP 13,000 and a carry-on at CLP 12,900 when you add them while booking. Waiting costs more: CLP 16,800 and 17,400 after booking, CLP 30,000 at the airport counter and CLP 34,000 at the gate. International flights price both bags the same, from USD 27.50 at booking to USD 65 at the gate. All figures are per bag starting prices that move with date, route and availability.

JetSMART publishes one 'from' price per bag rather than separate first and second bag fees.

Booking-time prices for domestic flights start at ARS 9,990 for a carry-on and ARS 12,590 for a checked bag in Argentina. Peru is priced in dollars, from USD 7.50 and USD 8. In Colombia the carry-on is the dearer item, from COP 59,999, against COP 38,300 for a checked bag.

A checked bag can weigh up to 23 kg and measure up to 158 linear cm. You can check up to 5 bags. Bags between 23 kg and 32 kg pay a flat excess fee at the airport, and JetSMART refuses anything over 32 kg.

Overweight bags of more than 23 kg and up to 32 kg cost from CLP 21,000 in Chile or USD 35 internationally, charged only at the airport. Oversize bags measure over 158 and under 230 linear cm, weigh up to 23 kg and cost from CLP 16,700 when booked, CLP 34,000 at the counter. Surfboards may reach 300 linear cm, and a packed guitar or bass can travel as oversize.

Each passenger can check at most 3 oversize items.

Yes, dogs and cats up to 10 kg including the carrier fly in the cabin, from CLP 41,990 on Chilean domestic flights or USD 80 internationally when added at booking. The soft carrier can't exceed 38 x 35 x 22 cm, rigid carriers are refused and it goes under the seat in front. Each passenger may take 1 pet, with 4 per flight, on direct flights only. Pets must be at least 3 months old, and there is no hold option.

The pet service is limited to direct flights without connections.

Yes, one stroller of up to 2 pieces travels free for a child under 6. Infants who fly on a lap without paying a fare also keep a small hand bag within the 45 x 35 x 25 cm limit.

Paying at the gate is the most expensive option: CLP 34,000 for a carry-on or checked bag on Chilean domestic flights and USD 65 internationally, against CLP 12,900 to 13,000 at booking. Wheels, handles and pockets count toward both size limits, so measure the whole bag before you fly.

No free-bag waivers are published for status members, cardholders, military or residents. The only included bags come with the FlexiSMART and FlexiSMART+ packs, plus free strollers for children under 6. Club de Descuentos is sold as a fare discount club, not a bag benefit.
