Easyjet may quite easily be the cheapest of the cheap airlines in Europe, so you might want to make your first stop there if that is what you are looking for. Howbeit, I would urge that you look not only to the cheapest of these services and service providers when you need to fly, but also at the quality of some of the services that they offer to you, in addition to their track records when they fly you around. This is why you might also want to consider other commercial airline services, such as Air Berlin, Ryan Air, and German Wings.
Come on, with hundreds of them all over the continent, I could not possibly name them all; but you could use your travel details as search criteria to locate the airlines that offer you the best of conditions for their services that suit your tastes. You could be anywhere, of course, as long as the flyer you are interested in travels at least that far – once you book your flight, you can travel with them and be glad that you did.
One of the best ways you can guarantee that you are indeed getting the cheapest rates possible, or rates closer to what you can afford, is to ensure that you bring the details you obtain from one flyer up against the ones that you got from the other. Piecing them beside each other allows you to do an instant comparison, and you know instantly which one of them you are going to be flying with… almost. You could make use of the services offered by an airline broker to make your effort faster and truer. Because they know the trade and you don’t, they can do things with and in it that you have no clue about.
There are other directories also that you may consider in order to get your cheap airlines in Europe comparisons, including EuroCheapo, WikiTravel, and mobissimo. Before you decide that you have the best deal already, you may do yourself some good by taking a look at their services first, and then perhaps you can decide for yourself.
