Transwede,
The services provided for FR (and other loco operators) are very differrent to full service ticket desk operations. For FR there is no need to be ticket trained, being able to use their website is sufficient as that is all AA do if they get a walk-in passenger wanting a flight.
As more and more of the European market is covered by lo-co operators there is less requirement for qualified ticketing agents; hence the move to other solutions.
