You have several options to get your cheap airfare to Paris.  All of these options include some planning.  Always plan to get your ticket in advance and try to have more than one day to use for a possible departure or return date.  It is not unheard of to get a ticket to Paris up to two and a half months before the flight departs.  Planning early is the key to finding cheap airfare to Paris.

There is a particular season when you will find the best deals, this ranges from January to the end of March and November to the begining of December.  Picking a day between Monday and Friday usually increases your chances of finding a lower price.

If you are unable to plan early, there is another option.  Simply visit all the websites of the big airlines that have flights to Paris and find the cheapest rate that way.

There are a couple low fare airlines such as Easyjet and Ryanair.  These are European airlines that give the lowest prices.  Even the regular fares of these carriers are lower than special prices from regular airlines.

Do not forget about websites like Expedia.com or Orbitz.com.  These will list all their best fares and include even cheaper fares that are taken from the biggest airlines.  Other similar websites are those that simply give you a search engine for travel sites.  These will provide almost all the airfare prices available and compare them for you.

Choosing your departure airport is also important.  New York will be a much better decision than Cincinatti.  This is mostly because there are simply more international flights going through New York than other smaller cities.  This will give you a higher chance to get a lower price on your ticket.

One last idea is to try getting a complete package, these could easily be cheaper than any other prices that you will find on the net.
