Learn when to book flights, how to spot mistake fares, and ways to use lesser-known tips like booking stopovers and tapping into rideshare rewards.

When is the best time to book a cheap flight? Do budget airlines actually save you money after all the fees? Scott Keyes, founder of Going (formerly Scott’s Cheap Flights), joins Smart Travel to talk about how to actually find cheap airfare — including how to time your bookings, when to use points instead of cash, and how to pounce on mistake fares before they disappear. He also busts some of the most persistent airfare myths (spoiler: incognito mode won’t save you money).

But first, Sally and Meghan break down the latest travel headlines, including new perks and price hikes for United Airlines credit cards, changes to the Delta-Lyft partnership, and why JSX credits might actually be worth something. They also share the best deals they’ve ever gotten on airfare and how to use free stopover perks.
