First, do your research: are there budget airlines unique to the country you're flying out of and where you're headed to? Booking with a budget Australian airline (Jetstar) from Sydney to Honolulu, then an American one from Honolulu to Montreal saved us over $400 each when flying back from Australia to Canada earlier this year. This allowed us to create a thrifty five-day stopover in Hawaii on our way back, which was less exhausting and a lot cheaper! Kiwi.com and AirWander are both great search engine for revealing cheaper routes like this that involve multiple airlines.
Before booking a flight, consider if the rate is cheaper if paid in another currency. Often budget airlines will make you pay in the currency of the country you're departing from, but this isn't always the case. An important note when doing this: make sure you're using a credit card that is free of foreign-transaction fees, otherwise your attempts to save money doing this will be lost! Our article on money matters for world travellers can help steer you in the right direction for the best credit cards for travel.
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.
You can sign up for an airline rewards card that earns points with a particular airline, or a more general travel rewards card that lets you redeem points across a variety of airlines. As a beginner card, we recommend the Chase Sapphire Preferred. You can earn up to 60,000 in bonus points after spending $4,000 in the first 3 months after your account opening. That's worth $750 when redeemed through Chase Ultimate Rewards, and more than enough for a domestic flight. There's also no foreign transaction fees, so it's the perfect all-rounder travel credit card. You can compare this card with other top credit cards.
