Is there any way to download all airports in Europe from OSM?
What I'm looking for is the Airport perimeter, (lines or polygons, dosn't matter)
I know that I could download all Europe, and then filter by attributes, but what I ask is if is there any way for do it directly.
Some kind of 'where', where I can ask for download ONLY the data
where column Aeroway is not null

You could use the OverpassAPI because it is not that much data.
You can easily construct a statement that filters for aeroway=aerodrome via http://overpass-turbo.eu
As always please be skeptical about the quality/coverage of OSM data and it's tagging.
Maybe it's worth to have a look at this page and parse the data (if open licensed): http://www.openflights.org
