About FO

FO operates as a regional carrier with a network built almost entirely around Argentina — 80 of its 90 non-stop routes stay within the country, which tells you exactly what kind of airline this is. It's not chasing long-haul glory. Instead, it's stitched together a domestic web anchored at Buenos Aires's Ezeiza International (EZE) and the city's closer-in Jorge Newbery Airport (AEP), with supporting operations out of Córdoba (COR) and the southernmost city of Ushuaia (USH). The total network stretches across 125,042 kilometres, which is respectable for a carrier of this geographic focus.

Why fly FO?

If you're moving around Argentina — and Argentina rewards moving around — FO's reach is genuinely hard to ignore. Nineteen routes out of EZE alone means connections to major cities and remote destinations that other carriers simply don't bother with. The Ushuaia hub is particularly worth noting; four routes out of the world's southernmost commercial airport suggests FO is one of the few realistic options for reaching Patagonia without a punishing series of layovers. The airline also dips into Brazil with eight routes, plus single connections to Peru and Paraguay, which gives it modest but useful regional coverage for travelers crossing into neighbouring countries from Buenos Aires.

Tips for booking FO

Book through EZE if you want the widest choice — 19 routes make it the most connected point in the network. AEP, just minutes from downtown Buenos Aires, is worth considering if your itinerary is domestic-heavy and you'd rather skip the long taxi into Ezeiza. The longest route FO operates is EZE to MCZ in Brazil at 3,641 kilometres, so if you're crossing into Brazil, check that corridor first. Because most of FO's strength is domestic Argentine flying, don't expect extensive international codeshare options — verify connections independently rather than assuming interline agreements will catch you if something goes wrong.
