Hello All, I was wondering what the prevailing theory was regarding mileage runs for flights that you have to take anyway. I know that typically most people only consider a flight a mileage run if it is at 5cpm or below, but what if you already have to take a flight? For instance, I have to fly ex CVG/DAY area to NYC with flights costing around $400 even with a connection netting a terrible 16cpm or so. If I can find some overnight routings through the west cost for $550 or $600 that drops the cpm to 9 or so, that still would be seen as a terrible mileage run, but the marginal cost (assuming the first $400 is sunk) is 5cpm. What do you all think? Thanks.
