Flight search that shows nearby airports?

[Horton55]

Flying to a big region (like northern Italy or southern Spain) – is there a good search engine that automatically includes nearby airports so you don't miss cheaper options 1–2 hours away?

Yep, that feature saves a ton sometimes. tripmydream - flight and travel search does a decent job with the "nearby airports" option – you can turn it on and it includes secondary airports automatically in the results. Helped me find a €60 cheaper flight to Bergamo instead of Milan Malpensa last summer. The map view is handy too. What do you guys use for multi-airport searches?
