For the most part, the USAirways Express network is remaining intact. As mentioned, US is converting to a be a low-cost airline, and if you think about it, look at all the different models of airlines that are claiming to be LCC's.
That being said, anything thats an EAS route is safe. The regional affialite, primarily Air Midwest (Mesa) that operates those B-1900 routes, along with a handful of routes operated by Colgan (Saabs), are basically being subsidized by the government. The majority of other routes will stay. Now that Shuttle America is gone as a USExpress operator, and the D-328's have been phased out......The Dash-8 is the primary turboprop being flown at Express. There are still those B-1900's, and Saabs, but the Dash fleet will remain as is. A few of the oldest ones left the fleet last year, but there are still an important part of the Express operation as there are many routes that cannot be flown with an RJ
, either due to airport limitations, like HHH for example, or that the route does not make economic sense to have an RJ
. The RJ
's are being rationalized by swapping some RJ
and prop routes. Some of the longer Dash routes or those out of DCA
will become RJ
, while some of the shorter RJ
routes on non-business routes out of PHL
will become prop.
