I'm pretty much the same if I'm going on holiday - I usually chose an exact city well before looking for flights rather than a country or an area.
If I'm flying back to my parents though, it's a bit different. There are a number of airports around them:
- one has flights daily but requires a 3 hour train journey
- another has flights twice a week and is a 1 hour drive
- another has flights daily, is a 1 hour drive, but is usually more than twice the price of the others
- another has flights daily, is a 2 hour drive, and the price varies
For this I usually just open SkyScanner (Adioso doesn't seem to have many low cost airlines in Europe) in 10 tabs or so and compare the results myself...
