A route that Liverpool would do well to see return is Oslo. It has operated by Ryanair in the past, in fact to two of their airports they used in Oslo. Presently there is no scheduled service, but regular charters by Enter Air. This is due to a large following of LFC supporters in Norway, which is also why Wideroe operate the Bergen route ( returning next year ). I feel Oslo would do well when you also add in other passengers who would want to visit Oslo / Liverpool.
