July 16th PIT-BWI #4248 - projected full but 41 seats for sale, 2 non-revs signed up
July 20th BWI-PIT #1535 - projected 6-10 avail with 47 seats for sale, no non-revs signed up
Might be a bit early to get a handle on how these flights will go. The 1st non-stops on both days are projected wide open. Hope this helps.
