I was talking to an AC agent the other day en route to ORD, she was mentioning that for every new fare idea initiated by AC, a new fare code must be used. Hasn't AC pretty much used up the alphabets?

Why can't there be a simpler structure in place for fares? There has to be a way to merge travel agents' fare codes with the ones online. Further, do we really need 3 separate Tango, Fun and Latitude codes? It makes life difficult for travellers and employees alike (I still remember how long the agent took to decide whether my Latitude fare was eglible for stand by or not).
