When booking international flights, consider playing around with currency conversions before booking. If your home country’s currency is currently strong compared to others internationally, consider switching to a weaker currency.
Check whether your desired flight has a cheaper price by visiting the international airline’s native website (not the English one that is sometimes generated). Maybe international airlines will offer at least a slight discount to passengers who book in their country’s native currency. This saves the company foreign transaction fees and isn’t impacted by constantly changing international exchange rates. While this travel hack may not always work, it’s possible that you could find a cheaper fare on a flight you’ve already identified as a good fit for your trip.
Fair warning, though: Be sure that the credit card you’re using does not carry a foreign transaction fee, or you may end up paying extra for your travel hacking.
Similarly, consider booking international flights in the local currency of the country you’re visiting for a potentially cheaper rate. Many airline websites have a toggle feature in the top right corner of the screen. Simply select the country you’re planning to visit and browse away.
