As a price micro-manager, I'd welcome an improvement in the price management pages : it can be very clunky at times going back and forth from route management, to specific route info, to 'group' route info (for all flights to the destination), adjust if reqd, then back again to route management, repeat ad infinitum : and I'm a small outfit, Eris knows how you bigger boys manage it.
I'm not sure how the process can be changed for the better : sometimes its easier to just do a general price adjustment, but that can not always be ideal for all your routes, so you end up going back in again a day later to check, adjust, *yawn. Having ALL the data/change points accessible from a single page would be good, but I can also see it being overwhelmingly complicated for less-seasoned players
I agree that as price is now a far greater influence, and can be key to making some routes profitable, be it due to demand, competition, compensating for imperfect scheduling, or whatever ; it does need to be made a less tortuous process. Perhaps the key is to enable us to see what we need to know on one page ; then the adjustment routine can be left as is ; the time saving would be from not having to go into the bowels of each route, those that look okay on that new page can be 'ignored' so the OP's ideas are in the right direction, for me.
