Not really an MR so not sure it belongs here. But I'm looking for any tips on how to do this, just making sure that it doesn't look strange from a cost accounting perspective. Corporate travel office is pretty lax - we don't have to pick the cheapest routing, as long as it's reasonable. So for a fare like this, I think would want to stay within $100-$150 of the cheapest fare that I can find on United (which is the $771 fare below).

I'm going from BWI-ARN in March 2013, 3/7-3/19 (flexibility a few days either side). Looks like BWI-EWR-ARN-EWR-BWI nets 8,860 for $771 (8.7 cpm, 500 elite min). But if I go BWI-IAH-EWR-ARN-EWR-IAH-BWI that nets 13,130 for $775 (5.9 cpm). Any other creative routings that I could try? Thanks in advance!
