IOSA
Not being an IOSA registered airline greatly inhibits your ability to sell tickets.
It will affect them in as far as QF will not code share with them after a certain date this year. I think its around July. QF will ONLY code share with IOSA cerified airlines as of that date.
So this will greatly affect their Norfolk runs. OA approached Air Vanuatu to codeshare into Santo because OA is finding it tough flying to HON for fuel whilst empty. Air Van, regardless of what they say, will not code share with a non IOSA registered carrier.
Simple.
