American and US Airways have begun phasing in codesharing. In conjunction with this, both US Airways and American Airlines are incentivizing their frequent flyers to credit flights on the other carrier to their home mileage account. No need to book a codeshare flight, just credit a US Airways flight to American — or vice versa — and earn 50% bonus miles.
US Airways is offering a 50% bonus on American Airlines flights between January 13 and March 2.
Registration is required. Flights purchased prior to registering do count and in fact even flights taken during the promotion period prior to registering will count as well (the flip side of this is that bonus miles don’t post right away). The offer applies only to American, American Eagle, and American Connection-operated flights, and not to codeshares operated by other carriers with an American Airlines flight number.
American AAdvantage is also offering a 50% bonus on US Airways flights for the same period of January 13 through March 2.
The promotion rules appear essentially the same as the US Airways offer.
You need to register for the American AAdvantage version of the promotion with code AAUSM.
With this offer a US Airways frequent flyer earns more miles flying American, and an American frequent flyer earns more miles flying US Airways, than flying the airline attached to their home program. Of course choosing to fly the other airline has its disadvantages — while there are some reciprocal elite benefits, upgrades aren’t yet one of them.
Still, this would have been great flying the US Airways Shuttle last week. Bonus miles are bonus miles, and they’re great when you’re going to take a flight anyway.
From the perspective of the airlines, presumably they hope this gooses travel on the other carrier. Although I’d guess that among their frequent flyers the ability to earn status miles and elite bonuses already would suffice. Nonetheless, this could help make the choice a bit more focal.
Eventually miles from US Airways Dividend Miles will be combined into American AAdvnatage accounts. I would be surprised if they don’t offer an opportunity to move miles back and forth on your own long before the two programs are officially combined likely a little over a year from now.
