The tool Sky scanner is one of the most useful and easy to use flight searches in Europe. This search will help you find and compare flights with taxes included.

The site is extremely simple to use. Type in your origin and select from a list of destinations. Then you will see airports and prices - click on the best deal and continue.

Next you will see either a calendar or a graph - the graph mode is the easiest way to compare prices and will help you line up return dates too.

After selecting your days, you will come to a new page where you check the live price. The price of your flight sometimes changes here - that is because the data on the website might be old. Sometimes the price goes down, but usually it goes up. This is because seats on the plane were sold in the time it took to be checked.

Following this, you will be redirected to the company's web site.

Note that the price including tax will not include all the evil charges airlines make such as baggage, credit card fees and so on.

Sometimes the website is a little bit fiddly - when you have to enter where you want to go, the text might disappear or change as if you clicked on the wrong list item. Its a minor problem, but sort of annoying when you are in a hurry.

Another thing that the site doesn't have is options to leave from nearby airports. Say you live in Luxembourg and you want to fly to Sweden, you would have to check the Luxembourg airport, then the Frankfurt Hahn airport then Brussels, the Paris all separately. It would be nice if this function was done for you.

To get around this problem you can select your destination as you origin in a separate window and check where the cheapest flights are, but this is not always reliable and takes extra time.
