Search flights from nearby airports. This is a very simple and effective trick to find cheap flights. Sometimes flights from local airport to your destination can be quite expensive while, on the contrary, flights from nearby airports can be really cheap. For example, international flights from Seattle are quite cheap when compared to international flights from Vancouver and the distance between the two cities is only 234 km (about a two and half hour drive). So driving or taking a bus to the nearby airport is sometimes a good way to get to your destination cheaply.
If you have to be at your destination by a particular time, be careful about waiting too close to your departure time before purchasing your ticket. If you do not have your seat reserved a week before you need to be there you run the risk of not being able to get a flight. This is especially true of flights to popular destinations and during peak travel season.
Years ago, if you wanted to fly between continents, you were mostly stuck with traditional expensive airlines. That’s no longer true. Budget airlines now service many long-haul routes, making it possible to fly around the world for very little money. Norwegian Airlines allows you to fly between Europe and Bangkok for about $250 each way. AirAsia offers crazy-cheap deals around Asia and Australia for as little as $100 each way. Indian and Middle Eastern airlines offer cheap flights throughout the subcontinent and Africa. You can fly most of the way around the world on a budget airline!
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.
