Cost to SYd via Adel $367+tax, yet Bali to Adel on exactly the same flight that Syd destination would use is $461+tax, almost $100 dearer! Or a flight to Adel via Bris two days later is $311+tax. Oh, the pricing structure of airlines ceases to amaze sometimes. By the way, I cannot disembark at Adel if I book the Den-Syd flight.
