I live about 15 min from BLF and 40 min from BKW.
Colgan provides the EAS service under US Express to IAD from BLF/BKW. Colgan has announced they are terminating service to BLF in mid-November, partially because of the EAS money to BLF being cut, but more importantly, they are getting rid of their B1900s on the East Coast and replacing them with Saab 340s. Apparently, the runway at BLF isn't long enough to SAFELY (their word) operate the 340. So, they apparently are using the safety card to really say they don't make money in BLF even with the EAS $$ coming in.
Colgan would do better if the service (or at least one or two of the three per day) went to CLT instead of IAD... but that makes too much sense, which is why I'm not an airline exec.
