Shelling out the dough for your flight and hotel may be the most painful part of going on vacation. Luckily, the handy app Kayak exists to ameliorate that grief. Its wealth of features are as vast as they are varied, including currency conversion, car rental and airport scrutiny.
But what you should really pay attention to is Kayak’s robust flight and hotel search, which is top notch. The app rounds up flight and hotel options from various sources so you can pick out the most convenient choice (or the most economical). You can even set price alerts to get notifications when fares tumble.
