ATP Flight School's
website has some really good info about airline careers. Be sure to check out the PilotJobs and BeAnAirlinePilot links. As was mentioned above, the commuters are sucking up pilots right out of school. In fact, there are several commuters offering sign on bonuses, which was UNHEARD of until recently. If I were to start over, I'd jump right in to the airlines for a couple of years, build up some good quality time quickly (twin turbine), and then have enough experience logged to choose a job that I'd want (commuter, airline, corporate, charter, etc. ).
I've been doing the corporate thing for almost eight years now. I'm pretty happy with the pay, equipment, and home time. Another plus is that I know almost all my passengers, since I see them almost every day. On the downside, I only fly about 200 hours per year, and as with most "low-use" corporate flight departments, I have a regular desk job at the company when I'm not flying. Thankfully, we're about to gain another company as a partner and it looks like I'll get to ditch the desk job.
There's a charter company at our airport that is trying to snag me to fly Citations, but the small pay increase and the lure of a jet isn't enough to override the 10-20 nights away from home per month!
If I was in a different place in life, I'd hit the airlines in a heartbeat. Flight schedules known way in advance, great pay, awesome home time, etc. But with a house payment and a new bride that wants to start a family, taking a $50k paycut isn't a good move right now.
Avoid cargo. Cargo, since it doesn't complain, is expected to be flown in some of the worst weather conditions. And some of the smaller companies have really poor equipment. You'd get really great experience though. Freight dogs are some hard-core dudes. But the risks are high.
There's even a bigger vacuum for pilots in the heli industry. Once you hit the golden 1000 hrs (probably by flight instructing) you'll be able to snag a job that pays pretty well. Just glancing through my latest salary survey, it looks like the typical "low" pay for heli pilots (not counting flight instructors) is about $45-50 with a peak of $80-100k. So it looks like you'll start off higher with helis but you'll cap a little sooner than flying jets. But the cost of training is something like 50% higher. I started working on my rotorcraft rating (the most fun I've had in an aircraft, btw), but I ended up buying a house, and that ended the training.
Whichever path you choose (fixed or heli), do your research and start off at a good school. There are plenty out there that specialize in aviation careers and have good ties in the industry, and you'll pretty much be guaranteed an interview with an employer after completion. And a lot have financing available to help defer some of the training costs. It's a big financial hit initially, but it pays off well relatively quickly.
And did I mention that it's fun? It certainly beats a real job!
