First of all, travel off-season. Check with the local tourism office to find out when their off-season starts when flying, either plan well in advance (ideally, 10 months to a year ahead) or at the last minute (two weeks or less before you leave) — these will give you the cheapest pricing.
Try to be flexible- you can save on fares by travelling mid-week, or choosing sunny Varadero, Cuba, over sunny Cancun, Mexico.
Find and book a package deal or an all-inclusive trip.
Save your health — check with your credit card company for existing travel or car insurance. Not applied for local restaurants to hotel fare or planned outings, all-inclusives may not be a good idea.
Brown bag healthy snacks and meals to avoid pricey airport or train food. Book a hotel room with a kitchenette, to save on meals.
A very important thing, consult with your travel agent to preplan trips; surf the Internet for immediate deals. Ask your travel agent where to change your money to get the best exchange rate.
