Edinburgh is Scotland's busiest airport, with flights to a very wide range of European cities, and many airlines compete on the popular ones. That means that even a week or two before departure, there is often a reasonable fare to somewhere interesting.
The key is staying flexible about where you go. If you have a destination fixed in your mind, last-minute fares can be steep. If you can pick from five cities, you will almost always find something affordable, and some of the best trips are the ones you decide on in a few days.
