weekends for arrival and departure from the airport.
Don’t search for or buy multiple tickets in a single purchase. Airlines always show the highest ticket price in a group of tickets. For example, if you are a family of four and searching for four seats, the airline will find four seats together and show your fare based on the highest ticket price. So if seat A is $200, seats B and C are $300, and seat D is $400, it will price those tickets as $400 each instead of adding up the individual ticket prices. Therefore, always search for tickets as a single person. Afterwards, in the checkout process, you can pick your seats so you and your family are sitting together.
If you are going to fly when everyone is flying, then you’re ticket is going to cost more. Try to be flexible with your dates. If you are dead-set on visiting Paris, go to Paris in the spring or fall when fewer people visit and airfares are cheaper. But if you want to go in the middle of August? You’re out of luck. Hawaii over Christmas? Good luck!
Indirect flights are the way to go. Although layovers can be a hassle - especially if you have several of them - flying indirectly to your location decreases the total cost of your flight. Direct flights are in high demand, and are therefore made more expensive by airlines. Keep at least one layover open as an option, and prepare to save more money by considering multiple layovers for a single flight.
Compare between different airlines (regular and budget) and between the different classes of seats offered! If you can enjoy business class on a budget airline for the same money you'd pay to fly economy on a more "prestigious" airline, more power to you. You end up in the same destination but get to enjoy a more comfortable, luxurious experience. Why not?
Airline search engines have made it really easy to search the entire world to find the cheapest ticket — you no longer have to search manually. While Kayak offers the “Explore” tool that allows you to put in your home airport and see a map of the world with all the flights on it, Google Flights also has a similar – and better – tool to use. If you are flexible with where you want to go (i.e., anywhere but home), use this tool to figure out where to go:
