Pros
Pro Best prices
Pro Comprehensive results
Kayak searches hundreds of travel sites to find all the possible flights to ensure you don't miss out on the best options. They have the most comprehensive results out of the competition.
One of the biggest advantages of Kayak that most of their competitors don't have is the choice of where to book after you have found what flight or hotel you want. This means you are not locked into a single vendor and can compare the various booking fees etc.
Pro "Explore" is awesome for trip planning
Kayak has a feature called "explore" that lets you answer the question "Where can I go for how much?" Explore is a fantastic tool for initially planning out your trip while finding the cheapest flights.
From CN-Traveler:
You punch in parameters for a trip and how much you're willing to spend to fly there, and your options magically appear on a map. You could punch in, for instance, that you want a maximum-four-hour nonstop flight in January to someplace where there's a beach and the temperature is between 70 and 90 degrees and they speak Spanish, and you don't want to spend more than $500 on airfare; Kayak will spit back your options.
Pro Gives traffic and public transport information
Needless to say that these features will give you better and more up to date feedback when you're online, but you can still use it on offline mode. You can think about alternative routes or which public transport would be best for you to use, so you'll always have choices.
Pro Be able to download and use maps even on offline mode
Another good thing about this app is that you can download a map of an entire country of just a specific region, such as a province or state. So if you won't be needing a complete map, this will save you a lot of storage space. But you should check the file size when you're planning to download several regions because you may end up with a bigger file compared to just downloading the map of the entire country.
Pro Get to your destination easily with its turn by turn navigation
It has a very convenient turn by turn voice guidance so you can keep your hands on the wheel and be stress-free while you're driving. If you just plan on walking or commuting, then you'll be able to know every step or transfer that you need to take and when.
Cons
Con Dishonest about prices
There are a large number of complaints against Kayak questioning their honesty. It's frequently reported that after booking on the site and enter your credit card information, you will be told to call Kayak as something went wrong.
You are then given a higher rate, or sometimes charged the higher rate without being told.
Con Poor customer service
There are many negative reviews containing complaints of very rude and unhelpful Kayak customer service.
Con ChatDeal connection
They work with ChatDeal which is a rip-off site, and only on payment page in small print does it state that Kayak takes no responsibility for whether the ticket actually exists.
