United is offering tons of Business Class award space for the next 11 months on its flights to Rio de Janeiro, Brazil and Santiago, Chile.

Screen Shot 2015-07-31 at 1.39.01 AM

Both routes will soon be flown by United’s brand new 787-9 Dreamliners with flat beds in Business Class. You can book either route for as little as 35,000 miles one way.

United 787-9 Dreamliner

The United 787-9 Dreamliner has 48 beds in Business class in a 2-2-2 configuration. I would choose a middle seat, since both have direct aisle access. If you choose a seat on either side of the plane, you’ll either need to climb over your seatmate or be climbed over during the flight.

Each seat converts to a fully flat bed with 6’6″ of sleeping space.

Miles Price

Between the United States and Argentina, United charges 30,000 miles each way in economy and 55,000 miles in Business Class.

But you don’t have to book the United award space with United miles. You can book the space with miles from any Star Alliance partner. If you want to book with another partner, search without signing in. Note the date, cabin, and flight number of any Star Alliance flights with a blue button in its Saver award space column; then call the airline whose miles you’re using to book the award.

Here are the prices charged by some other Star Alliance partners (economy/Business one way) with their transfer partners in parentheses:

UR = Ultimate Rewards, MR = Membership Rewards, TY = ThankYou Points, SPG = Starpoints

  • Asiana (SPG) : 25k/35k
  • Air Canada Aeroplan (MR, SPG): 30k/47.5k
  • Singapore (UR, MR, TY, SPG): 30k/50k
  • Lufthansa Miles & More (SPG): 30k/52k
  • United (UR): 30k/55k
  • Avianca LifeMiles (none, must buy): 30k/60k

United flights to South America do not have fuel surcharges, so no matter what miles you use you’ll just pay taxes of $53 roundtrip to Chile and $60 roundtrip to Brazil.

Award Space Picture

All the calendars below are for direct flights to and from Houston for two people. It is zero extra miles to start your award anywhere else in the continental United States, Alaska, or Canada and connect to Houston as long as you find Saver award space on for those connecting flights.

Yellow dates have Saver award space for two passengers in economy. Blue dates have Saver award space for two passengers in Business Class. Green dates have Saver award space for two passengers in both cabins.

Houston to Rio de Janeiro

The 787-9 Dreamliner starts flying on August 18, 2015.

Screen Shot 2015-07-31 at 1.19.28 AMBusiness Class award space is available over the whole schedule except Christmas, New Year, and Carnaval (February 5-9, 2016). Award space is particularly good in March and April , 2016.

Rio de Janeiro to Houston

The northbound flight is a slightly longer redeye.

Screen Shot 2015-07-31 at 1.28.10 AM

Return dates show similarly excellent award space in Business Class.

Houston to Santiago

The 787-9 Dreamliner takes over this route on January 5, 2016. Just like Rio de Janeiro, both directions are redeyes.

Screen Shot 2015-07-31 at 1.26.21 AM

Award space is fairly available in January, February, and March 2016, summer down there. April through June have plenty of economy award space.

More People

All the calendars above were for two people. I did one search for eight people from Houston to Rio in April and May 2016. Many of the dates have award space for eight people in flat beds!

Other Houston Dreamliner Routes

United is also placing its 787-9 Dreamliner on several other routes from Houston over the coming year: Frankfurt, Amsterdam, Tokyo, and Buenos Aires. None have very good award space in Business Class with Buenos Aires space particularly abysmal.

Bottom Line

There is excellent award space for two people in economy and Business Class from Houston (or elsewhere in the United States) to Rio de Janeiro and Santiago. United puts its 787-9 Dreamliner on the Rio route in a few weeks and on the Santiago route in January.

Just because the space is on United planes doesn’t mean you should use United miles to book. You can use any Star Alliance miles.

  • Asiana charges only 35,000 miles one way in Business Class, compared to United’s 55,000 mile price. You can transfer SPG points to Asiana miles in about two weeks.
  • Promiscuous transfer partner Singapore Airlines, a transfer partner of Chase, AMEX, Citi, and SPG, offers the routes for 50,000 miles one way in Business Class.
