At Faro (my home airport) you have a terrace with a good view to the ramp but the sun is in front of you. On the south of the runway, outside the airport, you very good places always with the sun behind you. Here you can see all the major european charter airlines.
Forget Seville in Spain, there's almost no traffic there and no terrace, only a couple of windows with glass.
At Luxembourg there are good places outside the airport but I didn't find them, also I didn't see any terrace.
At Budapest you have to pay to go to the terrace but the view is very good and many east Europe airlines can be seen there, good for photographers.
