GDPF,you've been quite clear...It seems as a fairly complexed thing to do in such a big airline.I suppose it eventually pays off...
I've heard different sorts of stories,although regarding an uncomparebly different airline,and system...AA has a system that,I guess,other majors use,in more or less unchanged form and shape...They fly,do if for flying sake,then get family,get bored with it,just try to make a buck stick to 'em,and get as much as days off...In the end,it all comes in form of a $(enter currency used in your habitat)...Too bad if you ask me,but,heck,no one does
LOL
