Few domestic flights in the world hold as much anticipation as the one connecting Jorge Newbery Airfield in Buenos Aires with Ushuaia, the southernmost city on the planet. Departing from the heart of the Argentine capital, travelers cover roughly 2,400 kilometers in just under three and a half hours, watching the landscape transform from the flat expanses of the Pampas to the snow-capped peaks of the Fuegian Andes plunging into the Beagle Channel.
The route from AEP to USH is primarily operated by Aerolíneas Argentinas, with seasonal additions from low-cost carriers like Flybondi and JetSMART, which typically use Ezeiza instead. Flying from the centrally located Aeroparque is a clear advantage, as the airport sits just minutes from downtown Buenos Aires, making early morning departures easier to manage. Most flights are operated with Boeing 737 aircraft, and demand for window seats on the right side of the cabin is high on the southbound leg, since passengers are often treated to spectacular views of the Andes and, on clear days, glimpses of glaciers near El Calafate.
Choosing when to travel depends on what you hope to find in Tierra del Fuego. The austral summer, between December and March, brings long daylight hours, milder temperatures, and access to hiking trails in Tierra del Fuego National Park. This is also peak cruise season, when Ushuaia becomes the launching point for Antarctic expeditions. Winter, from June to September, transforms the region into a ski destination centered around Cerro Castor, and the shorter days bring a quiet, atmospheric charm to the city. Shoulder months like April and November often offer a balance of fewer crowds and reasonable weather.
A few practical tips can make the trip smoother. Book early, as this is one of Argentina's most popular domestic routes and fares climb quickly during holidays. Weather in Ushuaia can change rapidly, so delays and occasional diversions to Río Grande do occur; building a buffer day into your itinerary is wise, especially if you have a cruise to catch. Pack layers regardless of the season, since temperatures can swing dramatically within a single day.
What makes this journey memorable is not just the destination but the sense of progression. By the time the aircraft begins its descent over the Martial mountains and banks toward the runway hugging the coastline, passengers understand why Ushuaia is called the End of the World, and why so many consider this flight one of the most evocative in South America.
