With festive celebrations already underway and 2018 fast approaching, now is the best time to start pre-planning for your New Year vacation. And if you're wondering how to score the best deals on flights, setting airfare alerts is the single best (and easiest) thing you can to do to save yourself some cash.

A variety of different flight deal websites and apps make it easier than ever to set custom notifications for price drops — DealRay and Hopper are two of the best. We also recommend that you set alerts for certain trips — something you can easily do on both Google Flights and Skyscanner. You can also enter your departure airport and destination on Airfarewatchdog.com to see the lowest possible ticket price on sale at the time, as well as the cheapest round-trip fares every month.

Another great tip is to sign up for email deals. Thrifty Traveler and Scott’s Cheap Flights are subscription services that will notify you when there’s a serious deal worth booking. Do a little research and you may just find a website that posts deals specifically for your location, for example, YVR Deals shares the best deals available currently from YVR Airport in Vancouver.
