It is best to check multiple types of sites before you book, including the provider’s own website as well as online travel agencies and metasearch sites. One tip to keep in mind: The more flexible you are, the better the deals will be. Moving your trip a few months from a destination’s peak season often means lower prices and smaller crowds. Flying out on a Tuesday or Wednesday rather than a Friday or Sunday can also save you money. It is hard to get a deal when you want to travel at a specific time to a specific place. Easier to find the best deals by being flexible about either the time of year or the location. But if you know you have no flexibility, you should look into gaining and using airline points and miles versus waiting on a deal that may never happen.
