Find airfare to Chicago and book your next trip now

Summer, from June to August, is the most vibrant time to visit Chicago. Temperatures range between 20°C and 30°C, perfect for enjoying the Lake Michigan beaches and festivals like Lollapalooza. However, it is high season, which means airfare to Chicago from Brazil will be more expensive. We recommend booking well in advance to secure direct flights to Chicago or fast connections. It is the ideal time for boat tours and walking along the Magnificent Mile, but be prepared for crowds at major tourist spots like Navy Pier and Millennium Park.

From September to November, autumn offers mild weather and stunning landscapes as the leaves change color. It is considered by many to be the best time to travel to Chicago due to the balance between pleasant weather and lower prices than in summer. You will find more attractive flight deals to Chicago and shorter lines at museums like the Art Institute. It is the perfect season for food lovers to explore the city's diverse neighborhoods. In November, Christmas decorations begin to appear, bringing a special charm before the intense cold arrives for good.

Winter, from December to March, is harsh, with temperatures often below zero and plenty of snow. If you are looking for cheap airfare to Chicago, this is the time, except during the end-of-year holidays. The city looks beautiful illuminated, and activities like ice skating at Millennium Park are popular. It is the ideal opportunity to find business class airfare to Chicago with significant discounts. Take the opportunity to visit indoor attractions, such as the Field Museum and the Shedd Aquarium, which offer refuge from the cold wind known as the 'Windy City'. Dress warmly and enjoy the low prices.

From April to May, spring marks the rebirth of the city. Although the weather can still be unstable and cool, tulips bloom all along Michigan Avenue. It is an excellent time to find airfare to Chicago on sale before the summer peak. The parks turn green again and the city breathes new life. It is a strategic period for those who want to avoid extreme cold but do not want to pay high July prices. You can get great values on international flights to Chicago and enjoy the city peacefully before the arrival of large crowds of tourists.

For Brazilians, the passport must be valid for the entire period of stay. A tourist visa (B1/B2) is mandatory. We recommend starting the visa process at least 6 months in advance, as interview lines can be long. Have proof of accommodation and travel insurance on hand when passing through immigration at O'Hare airport.

Chicago has one of the best public transport systems in the US, the CTA. The subway (called the 'L') and buses cover almost the entire city. Buy a Ventra card to make payments easier. Unlike Brazil, where a car is essential in many capitals, in Chicago you can visit almost everything using only public transport and walking, which saves a lot on expensive parking.

You cannot leave Chicago without trying the famous Deep Dish Pizza. It is a thick-crust pizza, stuffed with lots of cheese and sauce on top. Places like Lou Malnati's or Giordano's are classics. Another tip is the Chicago-style Hot Dog, which never has ketchup! Also try Garrett Popcorn, an addictive mix of cheese and caramel that is a local tradition.

To explore like a local, leave downtown (The Loop) and visit neighborhoods like Wicker Park, Logan Square, or Andersonville. There you will find independent cafes, record stores, and the true soul of the city. Instead of just Navy Pier, walk 'The 606' trail, an old elevated train track transformed into a linear park, much frequented by locals for runs and walks.
