First piece of advice,....don't take too much advice( negative) from disgruntled pilots.. Especially those who may have only been in the industry 2,3,4 or 5 years....

The job, in most forms, beats any 9-5 I can think of...

The only thing at your age that can make life more difficult is a long term relationship, or heaven forbid marriage and kids before you are ready. What I mean is, if you have some serious relationship as your just starting out, life will be difficult.. If you can hold off from having a serious relationship until your well into flying and have some experience then that will make life a bit easier... You'll have more options the older and more experienced you get. Plus, when your just starting out you will most likely need to be mobile.. Which relationships make more difficult...

Another thing is move to whatever base you get.. If you are the type that can adapt and make new friends easily you'll be all set... Some just can't let go of their friends and hometowns.. Thus commute, and end up usually hating the job.

Also as stated before.. The job is not that glamorous... You won't be scoring chicks on layovers, flight attendants aren't all over you're junk every trip, and typically the only people who are even somewhat impressed about pilot talk are older men.., and sometimes grandma aged women will think your pretty neat.

But when you're 24-30 and able to travel wherever you want while all your old friends are stuck doing the 1 vacation per year, or no vacations, you appreciate the job. ( my first airline job was at 22, was single and traveled to Florida monthly while my friends up in the NE never went anywhere)

If you get into the career because you enjoy flying, want to earn a fair amount of money eventually, and don't get into it for widebody Europe flights right away, you will enjoy the journey...
