Fly around Finland's capital — until now (2,3)
I believe the answer is:
so far
'until now' is the definition.
(both can mean up to the current point)
'fly around finland's capital' is the wordplay.
'fly' becomes 'soar' (soaring is a kind of flying).
'around' indicates putting letters inside.
'capital' suggests taking the first letters.
The initial letter of 'finland' is 'f'.
'soar' going around 'f' is 'SO FAR'.
(Other definitions for so far that I've seen before include "till now" , "Up until the present moment" , "to a certain degree" , "To this point" .)
