You can't rate them because it varies for individuals. Some people want closest base, some people want the one that gets them PIC fastest, some people are fixed on only one like Skywest. Generally the idea is if you don't want to spend too much time at a regional you go with the bottom feeders or prop operators like Colgan because they have the fastest movement different bases. If you want a stable place where you can build a career you go to AE or Skywest etc.
Well we have to better define the terms "stable place" and "build a career".
If one were to consider having to rot in the left seat of an RJ for 10 years, than yes, Eagle is as stable as they come. Expect to take home $500 a week for 10 long years. Are ya'll ready for that? As far as building a career, well knowing it will be 10 years before you get into the left seat, and about 13 years before you have the PIC time required to POSSIBLY get one of the few major airline jobs that may or may not become available, then yes, you'll be building a career at Eagle because you won't be moving on anywhere else. Unless you want to go to another regional.
And a new hire needs to consider how old they are when they get hired. If you are under 25, you may have a 50/50 chance of making it to a major airline. If you are older, your chances of merely paying your dues at a regional in preparation for a job at a major go down with each year older than 25 you may be. After all, if you are hired at 27 you'll be 40 years old before even having an outside shot at a major. Do people really want to become a new hire again at 40+, knowing no major airline will likely have upgrade times less than 10 years anymore? Even SWA has nearly a 10 year upgrade. And spare me all the talk about how things are going to miraculously change when mandatory retirements start again. Check and see what percentage of pilots actually make it to 65. Most are already gone by then. Mandatory retirement is not going to be this professions xanadu like many believe.
And with management clamoring ever more vigorously to place yet more and more, and larger and larger aircraft on regional property, you see your chances of making it to a major airline even more remote. What is mind boggling to me is to hear these regional guys wanting their regional airline to grow so they can see some movement, but while they may see movement at their regional, it is at the expense of movement at the place where everyone dreamed of going when starting this career...a MAJOR airline!! And it also doesn't help that current mainline pilots still refuse to do whats necessary to get these large RJ's on mainline property. They continue to give up scope, they continue to turn their nose up at any flying that is done in anything other than a Boeing or Airbus. What do you expect from them really, they have theirs, to hell with everybody else. Then they have the audacity to complain that all of their flying is going away.
If a new hire into this profession is counting on expansion, forget it! Our current ATC system is an embarrassment that flat out can't move current traffic on time. As the economy improves, we will once again have the oil price volatility again. It was 2 years ago, and oil was over 100 a barrel prompting the industry to cut capacity stating that the current capacity couldn't be sustained at oil over 100 a barrel. And it was that dumb luck, not managements mental acumen that has helped the industry limp by since 2008. Oil already is nearly 80 a barrel. It will be well over 100 during summer and sometime next year we will see 150 a barrel again. Management claims that fares need to be at their current dirt cheap levels just to fill up our current reduced capacity which is about 15% less than early 2008. What's going to happen when oil is 150 again. Are you new guys going to be willing to accept even lower wages than are currently paid?
BTW, not being sarcastic, just laying it on the line as bluntly as possible. I wish I had this kind of info when I got into this free-fall of a profession, although when I got into this in the 90's, the environment was much rosier, or at the very least, not as dark. These new guys today have no excuse not to know what they are jumping into these days. I don't feel a bit sorry for anyone getting into this profession after 2004 or so, when we all knew things would never be allowed to get back to even what we had in the late 90's.
