The next time you plan to fly and are flexible about which airline to use, try using one of these online tools for searching flights first. But, Google Flights displayed the results as quickly as you can enter the information, unlike the other online tools that require you to enter all the information and then wait several seconds for the results to populate. If you want to choose each flight leg separately, Google Flights might be the best option for "a la carte pricing." It is still one of the best online tools for searching flights, but, it doesn't always find the cheapest flights. Above the search results, the top row will display three different price points: cheapest, quickest, and best.
