We want to see the northern lights, how and with who (travel agency) could do it?
you can checkout this link www.giftexperiencescotland.com/flying..., its three hour flight and starts in evening, the only restriction is they go only October to March nationally. Scottish departures takes place at end of this year.
They give you a pass with a years validity for approx. £200, the phenomena is not guaranteed but a years pass give you flex.
Hope this helps!!
