The E170s are in limbo. While the mainline-MDA employees are furloughed and the airplanes transfer to Republic, they simply cannot staff the planes. MDA pilots are not biting in the amount they need to keep the planes flying. Pilots take a long time to train but the MDA pilots could have a shorter training. Republic thought mainline 170 pilots would be desperate enough to start over on thier own plane under kiddie Chataqa pilots.
As for F/As, no one wants to work there... they have a high turnover rate between people getting fired and now that the real airlines are hiring again, why would you want to work there? You could be a real US Airways f/a (west) so why be a replacement F/A? Only a couple MDA F/As have gone because they can have a PIT base.
The 170s Republic has now they seem to be broken all the time or a F/A has blown the slide. They have planes all over the place broken and half the time they ferry them. US Air has had to send out 737s, the 170s still at mda and PSA jets to reposition people that have been stranded due to Republics ineptness. The need to buy thier way out of that horrible deal, get US its planes back so the customers can get the service they deserve.
There will probably be more E170 routes cut, downgraded, or reduced because of the decision to outsource mainline planes to a start-up commuter airline that simply can't handle the schedule, longer routes, or an aircraft of that size. Messy contracted regional airlines have probably been US Airways worst service problem, now they are being used on mainline routes and directly replacing mainline employees and the old term "you get what you pay for" is being shown all over the system.
