About Sky Airline

Sky Airline is Chile’s low-cost airline, flying from Santiago across Chile and South America, with a sister airline in Peru. Fares range from Zero with a small carry-on to Full with a checked bag and flexibility. This guide covers power bank rules, check-in at Santiago, Patagonia and how it compares with LATAM and Aerolíneas Argentinas.

Founded in 2001, the airline switched to a low-cost model in 2017 and flies an all-Airbus A320neo and A321neo fleet, one of the youngest in the Americas.

Power Bank Rules on Sky Airline

New international (ICAO) rules apply from 27 March 2026:

  • Each passenger can carry up to two power banks, in cabin baggage only, never in checked bags.
  • Power banks cannot be recharged on board, and many airlines also ban using them to charge devices during the flight.
  • Up to 100 Wh needs no approval; 100–160 Wh needs approval from the airline. Keep them within reach, not in the overhead bin.

Check-In at Santiago

Online check-in opens 48 hours before departure. Santiago’s international terminal is separate from the domestic terminal, so check which one you need, and arrive at least two hours before domestic flights.

Families and Special Assistance

Infants under two travel on an adult’s lap, and pushchairs and car seats can usually be checked in free. Request wheelchairs and other special assistance at least 48 hours before the flight.

Flying to Patagonia and the Atacama

Domestic flights cover Chile’s huge length:

  • Punta Arenas and Puerto Natales are gateways to Torres del Paine.
  • Calama is the airport for San Pedro de Atacama.
  • Puerto Montt is the gateway to the Lake District and Chiloé.
