Indeed. It is all down to money. It is part of the outsourcing we are discussing in the other thread. Every part of the system is chopped up so that it is no longer a system. It used to be (in all companies) that one section 'handed off' to the next with good will to get the customer to the end result. Now, each section only want to get rid of the customer as fast as possible.
On the other hand, the customer has made it very clear that they want to pay the lowest price and all companies (not just airlines) have complied with ways of saving money. It is circular.
