Flying out of Chicago O'Hare
Chicago O'Hare is United's principal hub and one of the few US airports with meaningful nonstop reach in three directions at once — Europe, the Gulf and Asia. For the Midwest that matters more than it sounds: a traveller from Ohio, Michigan or Wisconsin who would otherwise connect twice can usually reach a single-stop itinerary out of ORD. The Devon Avenue corridor and the western suburbs around Naperville and Schaumburg make this one of the heaviest South Asian travel markets in the country, which keeps competition — and therefore consolidator inventory — unusually good on India routes.
What to know before you fly to São Paulo
Entry requirements for US travellers
This is the one to check carefully. Brazil has moved back and forth on requiring visas for US citizens, and the requirement has been reinstated and postponed more than once in recent years. Do not rely on what a travel site said last season — confirm the current rule directly with the Brazilian consulate before you book, and if a visa is required, apply early, because processing is not quick.
Best time to go
Brazil's seasons are reversed. April, May, September and October are the most comfortable in São Paulo. December to March is hot, humid and the domestic holiday peak, with Carnival — usually February or early March — the single sharpest fare spike of the year in both directions. June to August is mild and the best value from the US.
Airports and arrival
Guarulhos International (GRU) handles international flights and is well outside the city; the transfer can take well over an hour in traffic. Congonhas (CGH) is the close-in domestic airport and is a different place entirely, so check which one an onward flight uses. GRU is also the main connecting hub for the rest of Brazil.
Baggage
Brazilian domestic carriers charge for checked bags separately from the international ticket unless they are booked together. Booking the domestic leg on the same ticket is usually the cheaper route, and it protects the connection if the first flight is late.

Chicago to São Paulo — frequently asked questions
Fares on the Chicago–São Paulo route vary widely by season and how far ahead you book. We do not publish an estimate we have not measured for this pair; call our agents and they will quote the live consolidator fare for your dates.
Carriers on this route include Avianca, LATAM, American, Delta, United and Copa Airlines. Others serve it on one-stop itineraries, and the cheapest is not always a name you would expect — the lowest fare we have tracked here was on a carrier outside that list more than once. Itineraries offer nonstop from Miami and the larger gateways, otherwise one stop via Bogotá, Panama City or Miami, and total journey time runs about 6–12 hours. Which carrier is cheapest changes with the season and the fare bucket rather than staying fixed, which is why we compare them all on every quote.
Plan on 6–12 hours from Chicago O'Hare International (ORD) to Guarulhos International (GRU), including time on the ground if your itinerary connects.
Book three to five months ahead. The seasons are reversed, so the northern-summer months are often the value window, while Carnival and the December–February southern summer are the sharpest peaks.
Yes — this route has nonstop service, with nonstop from Miami and the larger gateways, otherwise one stop via Bogotá, Panama City or Miami. Nonstop is not always the cheapest option: a one-stop itinerary on the same dates is frequently a few hundred dollars less, and on a journey of 6–12 hours that trade is worth pricing rather than assuming. Frequencies change by season, so call us for what is actually flying on your dates.
O'Hare (ORD) handles essentially all of Chicago's international traffic; Midway (MDW) is domestic and mostly Southwest. For long-haul the choice is made for you, but if your itinerary starts with a domestic positioning flight it is worth checking whether it lands at the same airport your international departure leaves from — a Midway arrival and an O'Hare departure is a cross-city transfer, not a connection.
Often, yes. These are consolidator-rich corridors where the published fare and the wholesale fare diverge, particularly around the December and Semana Santa peaks when the cheap public buckets vanish months ahead. Agents can also reach inventory on regional carriers that US booking sites either do not display or display badly. SkyKaro's agents are reachable 24/7, and nothing is charged until an agent has confirmed the itinerary and the price with you.
