I don't know how often you visit Helsinki but I think you look at it with rose tinted spectacles.
Yes, they do have a third runway, some distance from the main terminal.
Yes, it was opened not so long ago.
It is built in what was once a forest - bit different to Heathrow, very few lived there or for several kilometres around.
The airfield does have a large remote stand and I have used it on every arrival and departure, bar one, during the past year as the work in progress has severely reduced the number of gate stands.
The buses may turn up on time, the engineer may be there on arrival unless there is industrial action of some kind - alittle more frequently than in the UK.
Of course today it was -20 and when you get off the bus, at the remote stand, you may find it rather cold waiting your turn to go up the steps.
Be very careful when the snow has melted and refrozen as you may slip when you get off that bus (I've seen it many times).
I think Heathrow do very well compared to Helsinki with five times the number of passengers!!
