My favourite spotter-spot at CPH, is right at the start of runway 22L, where the majority of landings take place. This makes for excellent landing shots.
From time to time, however, they decide to land at the opposite end, on runway O4R, making it rather difficult, if not outright impossible, to get any kind of landing shots. You can’t even see the planes (unless it’s the A380 – you can see that giant bastard from the Moon).
You can, however, get some fabulous shots of every departing rear end, as the planes take off right in front of you.
