Sky Airline’s cheapest fare — Basic (the old “Zero”) — gives you one personal item and nothing else: no cabin trolley, no checked bag, a randomly assigned seat. That personal item is the under-seat size, roughly 45 x 35 x 25 cm. If you turn up at a Chilean or Peruvian gate with a wheelie bag on a Basic ticket, you’re paying — and paying more than if you’d added it online. This is a classic South American LCC structure: the headline price you see on a deal site is the seat and the person, full stop.
The good news is the rule is consistent across Sky’s whole map. Sky is a short- and medium-haul carrier — Chile and Peru domestic plus regional international hops to Argentina, Brazil, Uruguay, Colombia and Peru — so there’s no long-haul exception that bundles a free bag the way North American carriers do on transpacific routes. On every Sky route the Basic fare excludes checked baggage. What changes by region is the fee: adding a bag is cheapest on domestic Chile/Peru flights and pricier on international ones. To get a checked bag built into the ticket you step up to Max (formerly Plus, one 23 kg bag) or Max Flex (formerly Full, two 23 kg bags).

Baggage by region & route
Checked-bag inclusion on the cheapest fare can depend on where you fly, not just the fare name. Here is what the lowest fare includes by route:
| Route / region | Cheapest fare includes |
|---|---|
| Domestic Chile / Peru (cheapest Basic fare) | No checked bag — add online ~USD 15-30 |
| Regional international (Argentina, Brazil, etc., cheapest Basic fare) | No checked bag — add online ~USD 30-50 |
| No long-haul / intercontinental routes | N/A — Sky is short/medium-haul only, so no fare bundles a free bag |
What each fare includes
| Fare | Personal | Cabin | Checked |
|---|---|---|---|
| Basic (was Zero) | Yes (~45x35x25 cm) | Paid add-on | No (paid add-on) |
| Max (was Plus) | Yes | Included (10 kg) | 1 x 23 kg |
| Max Flex (was Full) | Yes | Included (10 kg) | 2 x 23 kg |
What you actually get on a cheap fare
On a cheap Sky deal fare (Basic), assume nothing in the hold. You get the seat and one under-seat personal item — that’s it. There’s no free cabin trolley either, so even your roll-aboard is an add-on. If you only travel with a backpack that slides under the seat, Basic is genuinely all you need and the deal price is the real price. Anyone else has to do the math.
Budget the bag in advance, online — never at the airport, where the rate jumps. Reckon on roughly USD 15-30 each way for a 23 kg checked bag on a domestic Chile or Peru flight, and USD 30-50 each way internationally (it varies by route, date and where you buy it). On many trips it’s worth pricing the Max fare directly: once you need a cabin bag and a checked bag, the bundled Max ticket often lands close to Basic-plus-two-add-ons, with a real seat thrown in. Add the bag fee to the headline fare before you decide a Sky deal is actually cheap.
Oversize, sports & special items
Oversize and overweight checked items (over 23 kg or over 158 cm linear) carry extra charges and should be declared and paid in advance to avoid steep gate rates. Sports equipment such as bikes, surfboards, skis and golf bags, plus musical instruments, are carried as special/oversize baggage — they must be booked ahead, are subject to specific fees and size limits, and large instruments may need their own purchased seat in the cabin.
The headline 2025 change is cosmetic but worth knowing so you’re not confused at booking: in March 2025 Sky renamed its fare bundles — Zero became Basic, Plus became Max, and Full became Max Flex, while the Light fare kept its name. The airline stated the products and baggage conditions behind each fare were unchanged; only the labels moved. Sky remains a low-cost, short/medium-haul South American carrier, so don’t expect any North-American-style free-bag-on-long-haul exception.
Frequently asked questions
Does Sky Airline's cheapest fare include a checked bag?
No. The cheapest fare — Basic (formerly Zero) — includes only one personal item that fits under the seat. There is no checked bag and no free cabin trolley on any route; you add the bag as a paid extra or step up to a Max fare.
What size personal item can I bring free on Sky Airline?
All fares, including Basic, allow one personal item of roughly 45 x 35 x 25 cm that must fit under the seat in front of you (think a backpack, handbag or small daypack).
Which Sky Airline fare includes a carry-on cabin bag?
The cabin/carry-on bag (55 x 35 x 25 cm, up to 10 kg) is included on the Max and Max Flex fares. On the Basic fare it is a paid add-on, not free.
How much does it cost to add a checked bag on Sky Airline?
Buying online in advance, expect roughly USD 15-30 each way for a 23 kg bag on domestic Chile or Peru flights, and about USD 30-50 each way on international routes. Airport rates are higher, and exact prices vary by route, date and channel.
What is the checked baggage weight and size limit on Sky Airline?
Each checked piece must not exceed 23 kg and 158 cm in linear dimensions (height + width + length). Heavier or larger items incur oversize/overweight fees.
Does Sky Airline include a free bag on international or long-haul flights?
No. Sky flies only short and medium-haul South American routes and has no long-haul intercontinental service, so no fare bundles a free checked bag on the cheapest ticket. International Basic fares still exclude the hold bag — only the add-on fee is higher than domestic.
What changed with Sky Airline's fare names in 2025?
In March 2025 Sky renamed its fares: Zero became Basic, Plus became Max and Full became Max Flex, while Light kept its name. The baggage allowances and conditions stayed the same — only the labels changed.
How do Max and Max Flex differ for baggage?
Max (formerly Plus) includes a cabin bag plus one 23 kg checked bag and a standard seat. Max Flex (formerly Full) adds a second 23 kg checked bag and full flexibility with seat choice.
