So it may be finally time to try and use some miles...

I want to get my family from PIT-TLS (Toulouse, FR) roughly 7/20-7/27. I can give or take a few days either side, but there is an event prescribing my presence 7/23 that I just learned of.

I have AA miles (~240k), and was hoping for award travel... I know, high season to Europe and all, but AA did find me outbound tickets at the 60k rate, but could not find anything to get me home.

The outbound on hold is 7/21, taking AA PIT-ORD-LHR, 10 hours to kill in London, then LGW-TLS on BA.

Am I missing any creative options? Should I call OneWorld for this instead of AA?

Also, I could probably drive to an East coast city (thinking something like Boston, PHL or NY) if it would help, or take a train from Paris or Madrid... I've never been to France before (only once to Europe, and that was Ireland - not to knock Ireland, I loved it!) so am unfamiliar with options there. I don't think I want to rent a car, unless there is compelling reasons to reconsider.

So, any gurus help me do this? I could maybe use miles for 2 tickets and purchase two, if I have to go 100k per ticket. Most fares I have seen are $1300-$1500.
