No single flight search tool is best for everything. Here's what each of the major ones is genuinely good at, so you can pick the right tool for the job.
Google Flights
Strong for fast comparison and date flexibility — the built-in price calendar and "track prices" feature make it easy to spot a cheaper day nearby. It links out to book directly with the airline or a travel agency rather than processing payment itself, which means no extra booking fee, but also means it's a research tool more than a one-stop checkout.
Skyscanner
Good for "anywhere" or flexible-destination searches — you can search a whole month or leave the destination open to see the cheapest places to fly from your airport. It aggregates listings from airlines and third-party agencies, so double-check who you're actually booking with before you pay.
Airline websites directly
The most reliable source for that airline's actual fare rules, seat maps, and any loyalty program pricing. If you already know which airline you want, searching directly often surfaces fare classes or promotions that aggregators don't show.

Kayak and similar aggregators
Useful for side-by-side comparison across many airlines and travel agencies at once, with filtering by number of stops, airline alliance, or airport. Like Skyscanner, you're often redirected to book elsewhere, so read the fare rules on the final booking page before paying.
A practical approach
- Start with Google Flights or Skyscanner to understand the general price range and cheapest dates.
- Cross-check the specific flight on the airline's own site — prices should match, and you'll see the exact fare rules.
- Book wherever the total price (including bags and seats you know you'll need) is genuinely lowest, not just the sticker price.
When a search tool isn't giving you a good answer
If you've compared a few tools and still aren't confident you're getting a fair price — or the routing is complex enough that comparison sites keep returning confusing results — that's a reasonable point to get a second opinion from a person instead of another website.
