I once tried to stick up for pilot pay, as not being so bad, but I am beginning to see just how much people can make, outside of aviation. It isn't all peaches and cream, but I know of plenty of people who graduated school with starting salaries of $60K+, in various careers, including some, that just a few years later, are making six figures.
Money is not everything, but the airline industry is just way too unstable, for such low starting pay, and having to spend so much time to reach the better pay. Not to mention, a furlough means starting over, at year one, whereas in other careers, a layoff means getting another job, at the same pay, in most cases, or, using the experience from the previous job, to get a better paying job, than the one before.
You mentioned some of the higher paying jobs, not requiring a degree; what about the ones requiring a degree? Here are some fields, not so much specific jobs, that have high income potential, even from the get go.
Finance - Starting salaries can be on the high end. I've heard of people getting $60K starting salaries in the finance field, and making six figures just a few short years later.
Information Technology - I've seen plenty of $70K+ salaries to start, and many in the $100K+ range, with just a few years experience.
Pharmacy - As mentioned by others, and almost anything medical pays well.
There are many other fields, than just the above. They are just a few that come to mind.
My sister is currently in her first year of pharmacy school. It is a hard curriculum, but she will more than likely start off making at least $80K+, when she graduates.
FWIW, as a customer service agent/ramp rat for a regional airline, I just made my first year mark, in mid December, and made $22K. It is sad that a regional pilot makes that, or not even that, their first year, and for some, even their second year, etc.
I love flying, and it is all I have ever wanted to do. I am sure it is a fun job, and probably beats almost any job, in that category. BUT, sometimes it isn't all about fun, when you are trying to support a family.
As much as I love flying, with the clear instability, and uncertainty that now looms over the airline industry, I am seriously looking at stopping at my instrument rating, for now, which I start work on, next week, getting back in school, and pursuing other careers, whilst watching, and waiting for the dust to settle. As much as I have always dreamed of being a pilot; I think I can honestly say, I have achieved that dream, just not in a career sense. Maybe my dream is just better spent as a hobby, and pursuing a better paying, much more stable career. We will see. Life is full of surprises. I am just glad, that at just 23, I am able to see this clearly, and accept it, rather than being blinded by it all, because of a shiny jet.
