I don't typically "need" mileage runs, but I still enjoy them as I am in the group of folks who simply enjoy the art of flying and the travel experience. And of course it doesn't hurt me in maintaining Diamond status. I am on a MR similar to this itinerary on April 26-28, 2013 going MIA-JFK-NRT-SIN-NRT-JFK-MIA. If anyone else will be onboard let me know. Flights are all DL 782-173-621-622-172-1085.
