Lots of good advice here, and I particularly like what TFaudree and Zap said. I've never worked for a major airline, but I have worked for a small corporate flight department and a regional airline. I'll summarize my experiences at both:
Corporate:
I came in with low time (about the same as you), and worked my way up to a PIC type and was allowed as much rope as I wanted to hang myself with when I first started. I flew with a couple of very good pilots, and they weren't afraid to let me dig myself out of whatever holes I might create. I learned a lot, and for the most part I had a lot of fun doing it. Nice hotels, awesome expense account, some pretty fun destinations, etc. Our passengers were great, and I really enjoyed the direct contact and customer service aspect. The drawbacks with this job were that I didn't fly much (just over 200+ hours/year), which made it VERY tough for somebody with low time to eventually move on. Also, my first chief pilot was a total dick and made promises to me that weren't kept, threatened me with my job, etc. He also did some questionable stuff sometimes with the airplane operationally, and basically created a culture of fear. I was VERY close to quitting when he got canned, and a very good guy took over and made the job fun again. But trust me, that kind of crap happens fairly often in corporate, even in some of the bigger flight departments.
Regional Airline:
Before I got much older, and in an effort to get my TT up, I decided to give the airlines a try. I'm working for what is considered to be one of the best regionals for QOL/Pay, and despite my initial pessimism it has lived up to that promise in my case. No doubt I work harder, as I now block 70 or more hours/month compared to the 15-20 I did in corporate. I still have a decent amount of days off, but nothing like the weeks of time off (even a month on a couple of occasions) that I had in corporate. But the training is significantly better than what you'll see in corporate, and you will be exposed to a lot more weather and abnormal situations as an airline pilot. Without question, my time over the past year has made me a much better pilot. Despite what the loudmouths at some (mostly other) forums suggest, the pilots I've flown with here are consistently very good, unlike corporate that tends to have a lot of variation in the quality of guys you fly with. The drawbacks here are I have absolutely no idea when I'll be able to upgrade, and observing how some of the major US airlines treat their employees and contractors is sickening. Some of the majors have nothing but contempt for their employees, and it really makes me wonder if that's where I want to be long term.
The best advice anybody ever told me is this: Keep your options open, and take advantage of whatever opportunities come your way. Some of the most bitter people I've ever come across in this industry are the ones that were deadset on being a major airline pilot, or flying a GV, etc. You have absolutely no idea what life is going to throw at you, so do a good job and just try to have fun with whatever you're doing - things will probably work out that way.
