If you can get a *A award from East Coast USA to South Asia via Europe, then I wonder;

- How far West could your origin be ? ORD ? I imagine if you tried to do West Coast to Asia via Europe you would be exceeding some kind of MPM rule ?
- Could you do a stopover in Europe in one direction ?
- And am I remembering the rule for date changes on *A tickets correctly, allowed before departure, but no date changes after travel has commenced ?
