Use skyscanner.net. This neat website searches all airlines, big and small, and allows you to look for the cheapest rates out of your local, rather than getting bogged down with specifics. Meaning, if you know you want to go on vacation but aren’t too picky about where, this website will provide the cheapest flights to everywhere in the world from the nearest airports to you.
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.
Search at the right time. Turns out, there is a best time to search for flights. After several studies of domestic (to the US) air carriers, it has been determined that the best time to search for flights is around 3:00pm Eastern time on a Tuesday. Why? Around this time is when airlines release their discounted flight options, and look to fill up last-minute flights for the upcoming weekend. Therefore, save your flight searching for a mid-afternoon break on the nearest upcoming Tuesday.

Spirit Airlines offer without question the most stripped-down, no-frills flying experience of any carrier in the country, with the simplest option open to travelers — the so-called "Bare Fare" — allowing just one personal item on-board the plane. And while all that frugality has earned the carrier just two stars from Skytrax, there's no question that it has also helped to keep fares low—really low! Expect to pay around 40% less than the average budget fare for all of America, saving plenty of dollars for the tables of Vegas or the sands of Cancun!
Many of these budget airlines have their own airline rewards credit cards, and most of them offer a major signup points bonus. For example, the Southwest Rapid Rewards Plus card from Chase offers 40,000 points after spending just $1,000 in your first three months. However, a general travel rewards credit card such as the Chase Sapphire Preferred is the best option for most people, as you have the flexibility to redeem your points towards a wide variety of airlines and hotels. You'll receive 60,000 bonus points worth $750 through the Chase Ultimate Rewards program after you spend $4,000 in the first 3 months of your account opening, and the card features no foreign transaction fees.
