Search in the right time frame. Ok, 3:00pm on a Tuesday afternoon, got it. That’s not all though; searching a specific number of days from your flight is also necessary for getting the lowest price. Search at the earliest 3 months before your flight, and at the latest 18 days before your flight. It has been determined that the best deals are posted for flights about 6 weeks prior to their takeoff, so aim for about a month and a half before your trip to search for plane tickets.
Not only does it help to be flexible with dates and destinations but being flexible with the route you take is another way to get a cheap flight. Sometimes it’s cheaper to fly to London and take a budget airline to Amsterdam than to fly direct to Amsterdam. There are so many budget carriers around the world that taking advantage of a good deal to another city and then hopping on a budget flight to your destination is sometimes the best way to go. I had to go to Paris once; the flight was $900 USD, but I could fly to Dublin for $600 and get a $60 flight to Paris. It meant more flying time, but the $240 I saved was worth it.
If your country’s currency is currently strong compared to others around the world, search airfare in a country where the currency is weaker. For example, the US dollar is strong and the New Zealand currency is weak. I found a one-way flight from Australia to NYC for $1,000 USD but when I searched on the NZ version of the airline, I found the same ticket for $600 USD. It’s the same airline, same flight, and same booking class. It was just booked in a different currency. This tip does not always work, but it works often enough that it’s something worth trying if your currency is currently doing well.

Why it's awesome: Norwegian Air is one of the most aggressive and controversial airlines in the world. The low-cost carrier had drawn the ire of its US competitors by proposing a plan to operate trans-Atlantic flights using an Ireland-based subsidiary. The airline's critics claim that such a move would allow Norwegian to flaunt Norway's strict labor laws and use Ireland as a flag of convenience. Norwegian has denied these accusations. Regardless, Norwegian CEO Bjørn Kjos has won US government approval to launch ultra-low-cost trans-Atlantic flights from smaller airports in the Northeastern part of the country.
