International travel can be a great experience; it allows you to witness many new cultures and lifestyles. KAYAK processes over 2 billion travel queries annually and displays results from hundreds of airlines and third party sites, allowing it to find a variety of flight prices and options. It is not owned by either Booking or Expedia. Cons: I travel very light, was finishing up a 14 day trip around the world, couldn’t check-in online.

For instance, many travelers only book with Jetsetter, including a couple I met at Banyan Tree Mayakoba. Hot Tip: Flight Network prices are shown in Canadian dollars. GasBuddy tracks gas prices all over the country, so travelers can use the site — or its free mobile app, since you’ll be on the road when you need it — to find the most affordable gas station prices along their route.

In true ‘Wiki’ fashion, the page offers dozens of links on anything and everything related to travel and each specific destination. It also has a flexible date function and explore” options that help you pick destinations based on price, trip duration, or even theme (like a romantic getaway).

Priceline travel sites (including , Kayak, and Momondo) are a different story. Kayak’s app offers custom alerts where users can set filters on timing, price and location. Online travel sites may be convenient, but there’s plenty of room for error when booking a trip.

In some searches, I discovered that the flight options included by default with my vacation package had ridiculously long layovers or undesirable departure times (4:30 a.m., anyone?). Priceline basically offers one-stop shopping: Not only can you book your hotel room, but your flight, rental car, and cruise as well.
