Skyscanner and Google Flights are the two dominant flight search engines, but they work differently and excel at different tasks. Skyscanner is an aggregator that checks more sources; Google Flights leverages Google's data infrastructure for speed and features. Here's when to use each.

1. Skyscanner
Pros
'Everywhere' search discovers cheapest destinations from your origin — unmatched for open-ended planning
Checks more OTAs and airline websites than Google Flights
Month-view calendar shows cheapest dates at a glance
Redirects to booking sites including budget OTAs Google may miss
Cons
Slower search results — can take 10-30 seconds vs Google's near-instant response
Some displayed prices are from less reputable OTAs (Kiwi, eSky)
Occasional price discrepancies between displayed and clicked-through prices
Less intuitive interface for complex multi-city itineraries
Use Skyscanner when you're flexible on destination ('where can I fly cheaply this weekend?') or want to ensure you're seeing every possible booking option including smaller OTAs. Use Google Flights when you know your destination and dates and want fast, clean results with price tracking. The optimal strategy is to search both: discover options on Skyscanner's 'Everywhere' tool, then verify and track prices on Google Flights. The price difference between the two is usually small (€0-20), but Skyscanner occasionally surfaces deals Google misses.
