Thanks for the help. I called the AA RTW desk and they were as usual extremely helpful.
I got all the routing changes and a non dated open end leg in NA all done. And as long as I can make it to BDL by Sat AM and get the tickets reissued there I will no be charge a penny!
Obviously for the open leg I will have to pay $75. However, i was very impressed taht teh conversation started with the assumption I woudl have to pay $75 but the agent actually checked and confirmed that I did not if I went to a ticket office.
Top marks for AA!
