On this Travel Tuesday, why it may be best to hold off until a bit later to book your holiday vacation.

According to a new study, one in five Americans have already made their plane reservations for the holiday season.

Some sources believe that you may be better off waiting until after September to begin booking those flights and hotel rooms. According to hopper.com, the best time to buy tickets for flights in December is going to be in early October, and if you are hoping to travel for Thanksgiving, then they suggest waiting until the Halloween season to buy.

That being said, if you have special accommodations you would need, such as elderly passengers or a large family, it may be best to book early to ensure that your needs are met.
