Did you maybe mean DL5787 (I cannot find a 5757 in the DL system)? If so, the flight is op'ed by Comair on a CR7. The return flight is op'ed by Express Jet on a ERJ145. Both are small regional jets and should be a quick flight to PIT. For seats, go to: http://www.seatguru.com/airlines/Del...nformation.php
