American Airlines business class from Miami and New York JFK to São Paulo (GRU) books with Alaska's Atmos Rewards for 50,000 points one-way, plus roughly $18 to $26 in taxes and fees. Space has been reported on dates running into 2027, but award space changes daily, so search your dates before you earn or transfer any points.
What You're Booking
The flights are American Airlines metal, mostly the Boeing 787-9, which has a 1-2-1 business class layout where every seat has aisle access. Confirm the aircraft for your date before you book. Reported space is as many as seven business class seats on a flight, so a pair of travelers can often find two together, though not on every date.
Booking Strategy
Search the dates on Alaska and book there with Atmos points. An award-search tool helps if you're flexible, because the cheapest dates are scattered. Price each direction on its own, since the outbound and return can sit on different days.
Start from the dates you can fly, not the points you hold. If space shows up, earn or transfer only what the booking needs.
Earning Atmos Points Quickly
Three routes to 50,000 points:
Bank of America's Atmos Rewards Ascent Visa Signature has an offer of 50,000 bonus points and a $99 Companion Fare (plus taxes and fees from $23) after $1,500 in purchases within the first 90 days. The annual fee is $95. Bank of America's page carried a temporarily unavailable notice when I checked on October 17, so confirm the offer is open before you apply.
Marriott Bonvoy transfers to Atmos Rewards at 3:1, and Marriott adds 5,000 bonus miles for every 60,000 points you transfer. Marriott lets you move 3,000 to 240,000 points a day. If you have an unused Marriott balance, this is the quickest route that doesn't need a new card.
Bilt Rewards transfers to Atmos Rewards at 1:1, which is why the Bilt Mastercard sits on many travelers' shortlists.
Before You Go
US citizens need a visa to enter Brazil. Check the Brazilian government's e-visa page for the current fee and processing time, and apply well before your trip. GRU is outside the city, so allow time for ground transport when you plan your arrival.
Should You Book It
If you can fly on the dates that show space, 50,000 points one-way for lie-flat business class to São Paulo is a strong long-haul redemption. If the dates aren't open yet, don't earn points on a hope: search first, and move quickly when the seats appear.
