According to Airline Route, British Airways has begun operating its 787-9 Dreamliner on three routes from London-Heathrow:

Delhi
Abu Dhabi/Muscat
Kuala Lumpur

In 2016, it adds a ton of 787-9 destinations including several in the United States:

Austin from February 1
Newark from April 2
Philadelphia from April 9
San Jose from May 4
Houston from August 1
Boston from October 1

The British Airways 787-9 Dreamliner is exciting both because it is a brand new plane and because British Airways features First Class on the plane, which the British Airways 787-8 doesn't have.

These flights have fuel surcharges, but

Last month I booked myself Thai Business Class for 36,000 LifeMiles + $47 to get from Japan, where I spent five days, to Thailand to meet my friend.

I woke up the morning of my flight in Kyoto and took a train to Nagoya. Unfortunately all the sites I wanted to see in Nagoya were closed for New Year's Eve.

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.

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.

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.

American Airlines will start flying its 787-8 Dreamliners with economy and Business Class seating from Los Angeles to Shanghai on October 5, 2015 and Sao Paulo on November 5, 2015.

Award space is dismal in Business Class on both routings, which is a bummer since the product and Saver mileage price are fantastic.

United is putting a 787-9 Dreamliner on its only route to Argentina, from Houston to Buenos Aires, starting October 25.

Avianca recently began flying the 787 Dreamliner from Colombia to destinations in South America and North America. Soon it will also fly the Dreamliner to Europe!

This is exciting because Avianca's fully flat Business Class looks very nice, award prices on the long intra-South American flights are super cheap, and this is be the most comfortable way to fly between the United States and Colombia.
The Product
I just flew Avianca's angled flat bed on its A330 from Bogota to Buenos Aires.

United is releasing economy and Business Class award space on its 787-8 and 787-9 Dreamliners from Asia and Australia, not so much to.

I don't think there's a single MileSAAver award seat available in Business Class on the brand new American Airlines Dreamliner.
