Google sends you through to the list of available flights—so even if you don’t like the details of the cheapest flight (maybe there’s a long layover or no free checked baggage)—there is a list of other competitively-priced flights also going to London or Chicago or Montreal that same week. Users can also search by continent—so if you are looking to jet off to Europe or South America, but are unsure of what country to visit, Google can help you decide which destination is the most affordable book using google flights on google–flight.com/
