Flying to LA from Hawaii to turn around and fly the opposite direction to Sydney is ridiculous. But the deviation fee is only $100pp. That is really a modest price to pay for personal flexibility. Yes, you still have to pay for a hotel in Sydney when you get there. But you gain an extra day in Sydney and a chance to catch up on sleep before boarding the ship.
Fortunately, Regent was able to get us a superb alternative to connecting in California for our $100pp deviation. We fly nonstop from Vancouver, BC to Sydney arriving three nights before our cruise--just what we wanted. We have always found the deviation fee well worth the cost.
All of this on top of Regent's special air offer that puts in business/first at 40% of what we would pay if we purchased the cheapest tickets independently. We are happy campers.
