For YOW to OGG in February - round trip via ORD on UA with flat beds on the long flights, fully refundable D fare for 3800 per person.
Or, on AC in a 737, the price was never less than 6000 per person when I looked.
However, in AC's defense, if I were booking this today, another reason not to book on AC is that the flights we would have needed are sold out in J this many months out. So I guess they should have been charging even more?
