www.kayak.com is the website for doing everything related to travel. From ordering flights to hotels, car, and finding special deals in the area. The user interface of the website is very intuitive, it is very easy to travel from one page to the other. The load time is very good, no noticeable load time were seen except when searching for flights.
One of the strongest point about KAYAK service is on the database of the flight that is registered in KAYAK. Almost all of local and international airlines were registered in this website. In my country, LION AIR is one of the local airlines were also registered in the KAYAK website. Other thing that is recommendable from this website is the all in one approach of this company. Not only search for flights, you can also search for hotels, cars, exclusives promos in this website. Not all of the flight search engine are capable of doing that.
KAYAK also can compare prices between several airlines. You can also compare the travel times between the many available flights. So it is up to you to choose the best way to travel (cheap tickets vs short traveling time). You will be blown away in how the KAYAK can set up the flight. In conclusion, KAYAK is one of the bestof online travelling search engine today. Hope this review is useful
