What Are JetSMART and Sky Airline?

JetSMART Airlines and Sky Airline are both low-cost carriers primarily operating in South America. They focus on offering affordable flights by separating core transportation from optional extras like baggage, seat selection, and in-flight services.

While both airlines operate with a similar ultra-low-cost model, their service philosophies and network strategies differ.

Price Comparison: Why JetSMART Often Wins

One of the most important factors for budget travellers is fare cost.

JetSMART Base Fares

JetSMART typically advertises very low base fares that include:

Seat on the aircraft
Basic onboard safety items (no extras)

To add services such as carry-on bags, checked luggage, or priority boarding, travellers pay a la carte. This model allows passengers to pay only for what they need.

Sky Airline Pricing

Sky Airline also uses an à-la-carte model, but travellers often find base fares slightly higher on comparable routes. Depending on sales and promotions, Sky can match or beat JetSMART on specific routes, but JetSMART’s headline prices tend to be lower more consistently.

Best for:
Price-focused travellers who want the absolute lowest starting fare.

Route Network: Wider Coverage with JetSMART

A critical factor when choosing an airline is destination availability.

JetSMART

JetSMART’s route network extends across:

Chile
Argentina
Peru
Brazil

It includes many domestic routes as well as regional international flights. Travellers planning multi-stop trips within South America often find more options with JetSMART.

Sky Airline

Sky Airline also offers a solid route map, but it focuses more heavily on Chile’s domestic market and selected international destinations. Its network is valuable but not as extensive on certain cross-border routes compared to JetSMART.

Best for:
Travellers seeking greater flexibility and more route options in South America.

Fees and Transparency: JetSMART’s Clear Approach

Both airlines charge additional fees for services outside of base airfare, but the way these fees are communicated and bundled affects overall cost perception.

JetSMART

JetSMART’s pricing structure aims for clear transparency:

Base fare shown upfront
Optional items listed separately
No hidden charges in final checkout

This helps travellers estimate total cost precisely.

Sky Airline

Sky also lists add-ons, but many travellers report that the total price tends to increase more steeperly once baggage and seats are added.

Best for:
Passengers who want predictable pricing and fewer surprises at checkout.

Onboard Experience: Functional and Consistent

Low-cost carriers are not about luxury, but they should provide a reliable onboard experience.

JetSMART

JetSMART aircraft are straightforward and efficient:

Slim-line seats
Basic comfort for short/medium flights
No complimentary snacks or drinks

The focus is on getting passengers from point A to B affordably, not on free services.

Sky Airline

Sky Airline’s onboard experience is similar in structure, but individual aircraft ages and configurations vary by route. Some passengers report slightly more variable comfort compared to JetSMART.

Best for:
Travellers who prioritise cost over complimentary services.

Booking Flexibility and Policies

When comparing budget airlines, it’s important to look at cancellation and change fees.

JetSMART

JetSMART allows changes and cancellations through clearly defined pricing tiers. Earlier changes typically cost less compared to last-minute adjustments.

Sky Airline

Sky’s policies are also structured with fee transparency, but the overall cost of changes can sometimes be higher, particularly on promotional fares.

Best for:
Buyers who may need flexibility due to travel changes.

Luggage Regulations: Choose Extras Wisely

Both carriers charge for luggage, but understanding the details helps avoid surprises.

JetSMART

Carry-on bags often require a fee unless included in a higher fare tier
Checked baggage pricing is competitive
Online booking makes fees visible early in the process

Sky Airline

Sky also separates baggage costs, but travellers sometimes see higher incremental fees compared to JetSMART on the same weight categories.

Best for:
Passengers who travel light or are willing to reserve baggage during initial booking.

Customer Support and Digital Experience

Smooth digital experience and support matter for travellers.

JetSMART

JetSMART’s online platform and app provide:

Clear booking flow
Quick access to itinerary changes
Customer service options during disruptions

Sky Airline

Sky’s digital tools are functional, but some users feel they lack intuitive layout and consistent service response times compared to JetSMART.

Best for:
Users who prioritise straightforward digital booking and support.
