Get another one-way B-A to get you home when the project is complete.
This is within the rules.
I've been doing this for 10 years. Usually drive to city A, then commute A -> B -> A over the weekend, to take care of the Saturday night stay requirement. Always with the same airline, same FF#. Drive home when the contract is over.
Another advantage is that I always have my car with me, to avoid rental expenses.
