Especially for DM's logged in when DL shows higher fares. Most loyal DL fliers don't even consider price shopping, unfortunately to their own detriment. I just booked MSP-ANC for $397, but it was with UA. Had a $200 voucher so that reduced the cost to $197. Figure the value of the miles I will earn is at least $100 and my net fare is under $100

Too bad for UA that they have to discount the ANC fare so much to fill the plane. MSP-ANC is always packed on DL.
