I am not sure if this is the correct forum. Therefore, I will apologize in advance should I be in error.   

Is there anyway to check which low cost carriers have routes that originate from any of the Stockholm area major airports and the destinations? My wife and I used LCC last summer whilst traveling in Europe. We were most pleased with all aspects of the carriers' services. We would like to do some city hopping again this summer. As we have two free Continental Airlines flights from Newark to Stockholm, our jaunts by necessity must begin and return there. Thanks one and all for any responses and/or advice. Perhaps, even some ideas for an itinerary.
