If you want to have some extra spending money on your San Diego holiday, listen up! As every experienced jet-setter will tell you, don't book at the very last minute. Fares are generally more expensive close to the departure date. Also, look around online and compare your options. If your destination has more than one airport, you may be able to pick up an excellent deal by flying into one that's farther away. Lastly, another simple way to save some cash is be ready to book at a moment's notice. If you stumble on a fantastic bargain, don't think twice --- grab it while the opportunity's there.
