Wanted to get people's thoughts on doing a MR from ORD on UA. Often the CPMs from ORD on UA don't warrent a good MR. For those based out of ORD do you do position flights? For example recently I have seen PHL-SAN on UA for $159. Would you fly to PHL to get this price for example or just keep searching for decent fares out of ORD? Any other ideas / thoughts appreciated.
