I have about 250k FF miles with AA. I've lost faith in their quality over the years (lots of transatlantic business travel) so would like to book codeshare flights using miles (and some cash) for 4 business or prem-econ tickets on an airline that does a better job on long-haul flights. I'm especially leery now with the work slowdowns and aging equipment American is flying.
We're on the east coast in a minor city. Happy to fly into Shanghai, Beijing, or wherever. Trip would be June 2013. Any advice?
