TAP Air Portugal is the European airline with the most flights to Brazil, running up to 3 daily departures from Lisbon to Sao Paulo's Guarulhos airport. For US travelers, this means connecting through Lisbon with a 9.5-hour southbound leg to GRU. The total journey is long (16 to 22 hours), but TAP fares can be $200 to $400 cheaper than nonstop competitors, and the Portugal Stopover lets you break up the trip with a free stay in Lisbon or Porto. Executive class fares on TAP's Brazil routes are also significantly lower than what you'd pay on American, Delta, or United.
John F. Kennedy International Airport (JFK)
TAP connects JFK to Sao Paulo via Lisbon. JFK-LIS is about 7 hours, then Lisbon-GRU runs about 9 hours 30 minutes. Total travel time is 18 to 22 hours including connection. TAP runs up to 3 daily flights from Lisbon to Sao Paulo Guarulhos.
Newark Liberty International Airport (EWR)
Newark routes to Sao Paulo through Lisbon, with total travel time around 18 to 22 hours. The EWR-LIS leg on the A321LR is about 7 hours 15 minutes.
Boston Logan International Airport (BOS)
Boston connects to Sao Paulo via Lisbon, total around 17 to 21 hours. BOS-LIS is roughly 6.5 hours, and TAP's 3x daily Lisbon-GRU frequency gives good connection options.
Miami International Airport (MIA)
Miami to Sao Paulo via Lisbon runs about 19 to 23 hours total. While nonstop options exist from MIA to GRU on other carriers, TAP's routing via Lisbon can be cheaper, especially in Executive class.
Washington Dulles International Airport (IAD)
Washington Dulles to Sao Paulo through Lisbon takes about 18 to 22 hours. The Portugal Stopover makes the connection worthwhile for travelers who want to split the journey.
O'Hare International Airport (ORD)
Chicago to Sao Paulo via Lisbon totals about 19 to 23 hours. ORD-LIS is about 8.5 hours, followed by the 9.5-hour Lisbon-GRU flight.
Cheapest Months to Travel
March, April, and September tend to have the lowest fares. These fall between Brazil's summer holiday season (December-February) and the busy June festas juninas/winter vacation period. Roundtrips from the East Coast can start around $600 via Lisbon.
Peak Travel Seasons to Avoid
December through February (Brazilian summer and Carnival) has the highest fares. Carnival typically falls in February or March and prices spike 2 to 3 weeks around it. The Christmas/New Year window is also expensive.
Best Time to Book
Book 2 to 3 months ahead for the best fares to Brazil. TAP's high frequency on the Lisbon-GRU route means seat availability is generally good outside of peak holiday weeks.
Midweek Advantage
Midweek departures from the US (Tuesday/Wednesday) lower the transatlantic fare component. The Lisbon-GRU leg prices are bundled into the through-fare.
Time Difference to Keep in Mind
Sao Paulo is on Brasilia Time (BRT), UTC-3 year-round (Brazil ended daylight saving in 2019). That means Sao Paulo is 2 hours behind New York during EST and 1 hour behind during EDT. From LA, Sao Paulo is +1 hour during PST and the same time during PDT.
