Head-to-head: Kayak vs. Google Flight
kayak google flight search travel apps

The fight: Flight aggregators

Tools that pull from hundreds of booking sites simplify flight search. Which aggregator will get you to the beach first?


Kayak: Offers fare alerts and historical price charts. Shows fares that combine different carriers. More international options.

Google Flight Search: Lightning-fast search results. Flight Explorer feature lets you enter a date range and see the lowest fares for multiple destinations.


Kayak: Comparatively slow search results.

Google Flight Search: No mobile app or ability to set fare alerts. Only fares that include one domestic leg.


Kayak: The original triumphs. Remember, though, airline sites may have offers that don't show up on either, says George Hobica of Airfarewatchdog.com.

Availability: Both sites are available on their individual websites. Kayak is also available on the iPhone, Android and Windows Phone. Both apps are free.
