Bump. DFW fliers may know the answer here - I'm trying to book a trip to Dallas and there doesn't seem to be a way to get delta.com to search BOTH DFW and DAL at the same time (i.e. you can use NYC, CHI, or WAS to search multiple airports in a city). I want to book a single ticket with outbound arriving at DAL and return leaving from DFW but this doesn't seem possible.
I even tried using concur, and couldn't get such an itinerary put together.
