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.
I’m not exactly sure why DL doesn’t have an option to search for both DFW and DAL flight options but DL doesn’t have that many flights at DAL (only 5x to ATL) due to the whole WN/DL Gate fiasco going on at DAL. If you want to book an itinerary arriving at DAL and departing DFW on one ticket you could just book it as a multi-city trip.
