I too have had the experience of dealing with Agencies, not just AA, promises promises and more promises of jobs nothing happened even after constant phone calls, finally gave up and went out and found my job of my own back
I certainly dont have anything against any agency just wont bother using them again if I ever have to. They all promised loads of work and nothing ever came of any.
Good luck to anyone who gets work for me it was probably the wrong time.
Happy flying
