I've been reading about these great mileage runs some of you have been finding. Yet, I can't seem to ever price anything decent. I've put in multi-city itineraries and always get absurd prices. I've checked them far out in advance (even with the return the following day) still doesn't work. I'm checking for them out of ORD on UA's and AA's sites. Am I just not getting it, doing it wrong or simply not using the righ sites? Any help would be greatly appreciated.

Thanks
