There are two good reasons why you may be considering building up some American Airlines miles at the moment:
AA still awards 100% of miles flown when you credit economy BA flights, compared to just 25% of miles flown if you credit to Avios
The pros and cons of collecting AA miles are discussed in the two articles I link to above.
If you did either of the above and wanted to top up your American Airlines miles, here is a good opportunity.
Between July 1st and August 7th, you will receive a 20% bonus on conversions of Starwood Preferred Guest (Sheraton, Westin, Le Meridien, W etc) hotel points to American Airlines.
This is on top of the 25% bonus that Starwood gives to any airline transfer of 20,000 points or more.
This means that, for example:
10,000 Starwood points will get you 10,000 American miles
20,000 Starwood points will get you 30,000 American miles
The bonus is valid for multiple transfers during the promotional period. No registration is required.
