Looking for advice on making my RETURN journey to DUB into a mileage run (or lowering the cost of the itinerary below). This trip is not a discretionary one, but I would like to maximize my miles nonetheless.

My schedule does not permit me to change the outbound.

On the return I want the most DOMESTIC connections possible as international connections are more irksome.

I would consider returning to a different European city and/or changing the return date.

Who is the best person to book/work this (i.e., AA or Travel Agent??)
TIA
