Travelling would always be equivalent to spending. But spending money during vacation doesn't have to be that much. Here are five tips to keep in scoring cheap flights when travelling.

1. When to book for a flight- According to USA Today, for domestic flights, check prices on Tuesday afternoons. This is an old tip but still valid because most U.S. carriers continue to release sales on Tuesday morning, and competitors quickly drop their fares to match the better deals.

2. Befriend budget airlines- Budget airlines offer significantly cheaper tickets than their full-service counterparts. But this comes with compromises such as less leg room and no "free" food/drink on-board (which is normally covered in your higher-priced ticket with full-service airlines).

3. Places to fly- The are good deals to Boston and Denver and nicer prices to Chicago, Seattle and Washington, D.C. As for Europe, there have been incredible deals throughout the fall and those will continue into the winter.

4. Paying through other currencies- 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. Make sure you're using a credit card that is free of foreign-transaction fees.

5. Non-stop vs. connecting flights- Compare the price of non-stops with connecting flights. Sometimes adding a stop to your route will save you money and it might be enough to endure the extra-long flying day, says thrifty nomads.
