Wideroe, which is part of SAS, flies into Bodo (ferry) and also to Svolvaer which is actually on the Islands and the nearest to the climbing (30mins). Around £350 UK - Svolvaer
Cheapest way is probably now to fly to Harstad/Narvik (Evenes) with Norwegian.no (the budget Norwegian airline) Around £150 Stansted to Evenes then 2 hours drive to climbing.
Either way you change planes at Oslo (Gardermoen) so get there as cheap as you can.
