There are many factors that influence the price of airline
Although it is arguably quite tough to save up enough miles to get a free flight, using the miles that you've accumulated to offset ticket prices or upgrade seats can still help you save some serious money. Taking advantage of the bonus offers you get when you sign up for top travel credit cards is definitely the easiest way to collect enough miles for 100% free flights.

When you do find small airlines, even if they are listed in a search engine results, it often pays to check the company site which may reveal exclusive online offers not found in a regular search engine. For example, when flying in Western Canada, I found that Hawk Air, a small and local company offers weekly deals on certain days. Be sure to double check!
Follow airlines on social media sites. You may feel silly adding an airline to your “liked” pages on Facebook or following them on Twitter, but the benefit of doing so is the special offers you’ll receive. Airlines want to reward regular customers and encourage them to continue flying with them, so they will often advertise special low rates and discounts via social media sites only. Follow as many airlines as you can for the best chances of getting a sweet deal.
Not only does it help to be flexible with dates and destinations but being flexible with the route you take is another way to get a cheap flight. Sometimes it’s cheaper to fly to London and take a budget airline to Amsterdam than to fly direct to Amsterdam. There are so many budget carriers around the world that taking advantage of a good deal to another city and then hopping on a budget flight to your destination is sometimes the best way to go. I had to go to Paris once; the flight was $900 USD, but I could fly to Dublin for $600 and get a $60 flight to Paris. It meant more flying time, but the $240 I saved was worth it.
