Update 11/1/14: I got the 7,500 miles.

Saturday I went to a Cadillac dealership in La Quinta, California to test drive a Cadillac to earn 7,500 American Airlines miles.

Unfortunately the deal is now dead as View from the Wing reported (and no, I don't have any idea whether your scheduled or completed test drive will earn the miles.)

I'll post my experience anyway because these test drive promos in which you can earn something like miles or a prepaid gift card are common enough.

What was the process?
How long did it take?
Did I have to

US Airways and American Airlines legally merged in December 2013, but the two airlines maintain separate frequent flyer programs

Qantas is refurbishing its A330s with "fully flat beds in business class." Right now the A330s serve the following routes.

Sydney-Melbourne
Sydney-Brisbane
Sydney/Melbourne/Brisbane to Perth
Sydney/Melbourne/Brisbane to Singapore
Melbourne/Brisbane to Hong Kong
Sydney-Bangkok
Sydney-Jakarta
Sydney-Manila
Sydney-Honolulu
Sydney-Shanghai

I have medium hopes for the new beds, which will roll out starting in December 2014. The reason I am not more excited is that the picture accompanying the press release looks to me like an angled lie flat beds, not fully flat beds.

This jives with my experience in business class on the Qantas A380.

You can get 7,500 American Airlines miles for test driving any new Cadillac, and you might not even have to do the 10 minute test drive.

From the promo page:
Right now, AAdvantage® members can earn 7,500 AAdvantage miles when you test drive any Cadillac* vehicle, including the striking 2015 CTS sedan with available adaptive cruise control and available OnStar 4G LTE with Wi-Fi®**.

You can get from anywhere in the United States to tons of destinations in the Caribbean for 20,000 US Airways miles roundtrip or 25,000 American Airlines miles.

Both deals rely on the airlines' off peak award charts. US Airways' off peak dates are September 1 - 30. American Airlines' off peak dates are September 7 - November 14.

Both airlines, as well as Delta and United, normally charge 35,000 miles roundtrip in economy to the Caribbean.

For a long time, a major weakness of American Airlines miles has been that American Airlines Business Class featured exclusively angled lie flat seats.

There are four Business Class award seats available every day in June 2015 on Japan Airlines' flight from Los Angeles to Osaka, Japan. Hat tip to reader Oren for passing along the tip.

The award space is bookable with American Airlines and US Airways miles much for as low as 50,000 miles each way. There are excellent connection options to and from Los Angeles and Osaka, so this space effectively connects all of the United States with all of Asia.

Unfortunately the seat servicing the route is angled lie flat.

Reader Steve passes along a great deal for people with lots of Marriott points.

Until October 31, 2014, you can get a 20% bonus when you transfer Marriott points to American Airlines miles.

This includes Marriott-points-to-miles transfers and transfers of Marriott points to hotel and air packages.

What are hotel and air packages?
Why are hotel and air packages often a better deal than just transferring to miles?
What airline transfer partner of Marriott points is always 10-20% better than other options?

Marriott points can be transferred to airline miles of most major airlines.

Marriott and United launched a partnership
