Santiago → São Paulo
A medium flight from Chile to Brazil. Same local time zone at both ends.
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.

Arriving at
GRU
São Paulo/Guarulhos–Governor André Franco Montoro International Airport
Brazil's financial capital
São Paulo is Brazil's largest city and financial engine, a dense forest of high-rises with no single historic core, spread across an inland plateau rather than a coastline. A commuter rail line reaches a station near Guarulhos Airport, with an automated people-mover covering the final stretch to the terminals on a limited evening schedule; most travelers still arrive by bus, shuttle, or car. The city is known for serious year-round traffic and a helicopter culture among executives trying to avoid it. It also has one of Latin America's deepest restaurant scenes and a dense, varied immigrant heritage, from Italian to Japanese.

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.
