Colgan has traditionally operated in the Northeast flying a mix of B-1900's and Saabs, under the USAirways Express name. Some of the service is at-risk, while a lot is Essential Air Service routes.
In the past 6 months, they were awarded a contract to fly turboprop routes as Continental Connection out of IAH
. This replaced Skywest, as said by offering a slightly larger aircraft and more advantagous costs. Thus, the rapid build-up of Saab operations in Texax.
Hence the rapid hiring at Colgan. They have been quickly gearing up for operations in Texas which has strained the company. Many people who start out at Colgan have jumped ship for the larger regionals like Pinnacle, Mesaba, Comair, Trans-State, etc. The addition of numerous more Saab aircraft has required significantly more crews.
The rumors about new fleet types are unfounded. The Saab2000 won't happen, as there are only about 3 currently operated in the United States, thus a complete lack of support services. They simply are not readily available
