It's currently passenger limited for the worst case 15 kt. downwind landing on 6400' long runway 02, the official length of which is reduced to 5036' by certifying agency ASSI. As Airlink gains experience they expect to always land into the wind on 20 and remove the restriction. The difference in reserves between Remote Island and an ASI alternate is only about 15 minutes. It's vitally important that a once-a-week service always lands at the destination. Going to ASI probably would run the crew out of time.
