The question should be which regional does this NOT affect? According to recent list I found, these are the airlines that operate some form of EAS service;

Mesaba
Great Lakes
Sea Port
Skywest
Pacific Wings
Air Choice One
Cape Air
Colgan
Chautauqua
ASA
Gulfstream
American Eagle

Their could be others as well. This will affect a lot more of you then you think, and a few of these companies stand no chance of surviving without the EAS program. Do the math, that's a lot of pilots, crews and people in general that are out of jobs.

But hey...I have a big name airline on the side of my plane...so I will be just fine!
