San Cristóbal is served by San Cristóbal Airport (SCY). It provides a vital air link from mainland Ecuador, with all commercial flights arriving from either Quito (UIO) or Guayaquil (GYE). There are no international flights or regular commercial inter-island flights into SCY; travel between islands is via boat. SCY offers an alternative to the busier Baltra airport, often providing a more relaxed arrival experience into the Galápagos.
The market for arrivals into San Cristóbal is served by the same carriers operating to Baltra, with limited competition. Avianca Ecuador and LATAM Ecuador are the primary operators on the UIO-SCY and GYE-SCY routes. EQUAIR may also operate on this route, providing a lower-cost option into SCY. Frequency is lower than into Baltra.
To find the most affordable flights to San Cristóbal, you must book your ticket from the mainland as part of your round-trip Galápagos itinerary before you travel to Ecuador. Book your UIO-SCY or GYE-SCY flight at least 2-3 months in advance, especially for peak seasons. Compare Avianca, LATAM, and EQUAIR for the best available fare into SCY. While prices are consistently high due to regulation and distance, flying mid-week into San Cristóbal may offer a slight discount. San Cristóbal is an excellent choice for starting or ending your Galápagos cruise or land-based tour on that specific island, saving a long ferry ride from Baltra — but note that flights into SCY are generally not cheaper than into GPS (Baltra), so choose based on itinerary, not price.
