Yes, you can travel without your parents at age 17, but the requirements differ between domestic and international travel. For domestic flights within the U.S., most airlines consider a 17-year-old an adult; you can fly alone without "unaccompanied minor" services, though you must carry a valid government-issued photo ID. For international travel, the process is more rigorous. Many countries and airlines require a Parental Consent Letter (notarized) signed by both parents to prevent international child abduction. This letter should include travel dates, destinations, and contact information. You will also need a valid passport. While you are technically a minor until 18, 17-year-olds are generally granted significant independence by airlines, provided they have the correct documentation to satisfy border officials at their destination.
