Dont forget that they are also dumping a lot of C-check work on to the B-checks.
Whats old becomes New again. Years ago AA did tons of third party work. Crandall got rid of most of it saying 'why should AMR help other airlines make money?'. I never agreed with that I figured why not make money off them? Unlike selling tickets you know how much you are going to make before you do the service and it can only become more(depending on what you mechanics find) not less. Dont man for the work, just call OT.
