If you want to have some extra spending money on your trip to Geneva-on-the-Lake, then listen up! As any seasoned traveller will tell you, don't book at the very last minute.

Fares often differ depending on the airport you jet into. Be sure to compare prices across air carriers as well. Last of all, another easy way to save some cash is be ready to book fast. If you see a terrific bargain, don't think twice --- grab it while the opportunity's there.
