How to Actually Find Cheap Flights for a Solo Trip

Most cheap-flight advice stops at “use a comparison site,” which is true but incomplete. The bigger lever is flexibility, and specifically how you use it.

Search with flexible dates turned on, most search engines (Google Flights especially) let you view a whole month's prices at once, and the difference between the cheapest and most expensive day to fly can be substantial, sometimes hundreds of dollars on the same route. If your trip dates aren't fixed, this alone usually beats any other trick.

Search in incognito mode, or at least be aware that repeated searches on the same route can show rising prices on some platforms. It's debated how much this actually happens versus normal price volatility, but it costs nothing to search privately, so it's worth the habit regardless.

Set a price alert and wait. Google Flights, Skyscanner, and similar tools will email you when a route's price drops. For a solo trip with flexible timing, setting an alert a month or two out and booking when it dips is consistently more effective than searching obsessively and booking out of impatience.

Consider nearby airports on both ends. Flying into a secondary airport near your destination, or driving a bit further to depart from a bigger hub, can meaningfully change the price, especially on routes served by budget carriers that don't fly into major airports.

Book one-way flights separately when it makes sense. Round-trip isn't always cheaper, particularly on routes mixing a full-service and a budget airline, and pricing each leg separately sometimes beats the bundled round-trip price outright.

Last, don't ignore layovers you'd normally filter out. A longer layover, especially one over 8 hours, can sometimes be turned into a free mini stopover, more on that below, and routes with less convenient connections are reliably cheaper than the direct or near-direct options.
