Santiago → Buenos Aires
A short flight from Chile to Argentina. No clock change on arrival.
Chile's capital in the valley
Santiago sits in a long valley between the Andes and the coastal mountain range, close enough to the peaks that snow-capped summits are visible from the city on clear days. The metro doesn't yet reach the airport; a dedicated line is planned, so buses and taxis cover that trip for now, while the existing network serves the rest of the city well. Smog can build up in the valley during winter temperature inversions, when the surrounding mountains trap pollution close to the ground. It's the springboard to well-known skiing and wine country, both within a couple of hours' drive.

The Paris of South America
Buenos Aires is a grand, European-flavored capital of wide boulevards and sidewalk cafes, built on the flat pampas along the Rio de la Plata. Ezeiza Airport sits well outside the city, with no rail link; the Tienda Leon shuttle bus, taxis, or rideshares cover the roughly 40-minute drive depending on traffic. A separate, closer downtown airport (Aeroparque) handles most domestic flights, so check which one your itinerary actually uses. Buenos Aires keeps notably late hours, with dinner often starting after 9pm and nightlife running well past midnight.

Notes from the product.
Small updates, route observations, and clearer explanations for how the app keeps evolving.
Type less, wait less, wonder more
Airport search now understands metro codes and old city names, FlightSide loads noticeably faster, and a new Feeling lucky button chooses a flight for anyone without one in mind.
A closer look at the route, not just the seat
FlightSide now shows the two cities and key details about the flight alongside the seat recommendation: confirm you picked the right airports, read the time change off two clocks, and check the return leg.
It's all about the sun (after all)
Not all sunlight reaches the side windows. FlightSide now weighs the sun’s angle to the cabin and shows twilight along the route.
