Iceland
Iceland expensive in general. The flying here seems however to be cheaper than in the rest of Europe. Less taxes etc.
If you stay in a Hostel or some low cost housing, you could manage to keep costs down. Shop sensibly in the supermarket etc. If you fly a bit of hours it should more than make up for that cost.
Fares vary in price with the airlines. Can cost from 200 euros and upwards.
Flying here is easy, airspace restrictions are minimal, sunlight almost 24/7 in the summer and the weather quite mild.
If anyone wishes more information ask away...
