3. Online Travel Agencies are similar to meta-search sites in terms of fare search but offer booking service. These might be useful when you need hotels and cars in addition to a flight. Some airlines may not participate in their booking systems. Examples are:

Before you make a purchase, you should check for these key terms:

  • Non-stop Flight: A flight with no stops or connections to your destination.
  • Direct Flight: Means there will be a stop(s) but the plane you are on will not change. Your plane will make at least one stop at a mid-point airport.
  • Connecting Flight: Requires at least one change of planes en route to the final destination.
