Can you fly international from NY to Odessa (w/ connection fly in Warsaw) by myself, and what papers ?

As long as you have your pport you may travel alone. The "special request" is if your parents want to pay to have you escorted as an unaccompanied minor. It costs about $100 each way, and you sound old enough to travel alone (if you are over 12). Check out the TSA website for cool movies about what you can carry through security and tips for kids traveling alone.
