Wife self just did the SYD/HNL/SYD in J on Jetstar last week, I must say was rather surprised at the excellent service and the food too, lucky, guy in front hardly had his seat declined and on return had bulkhead seats lots room, feet could just touch wall. No back seat AVOD but had my iPad loaded with movies I rented before departure and wife and I watched a few, audio via a dual headphone adapter (have 2 sets Bose noise cancelling headphones).
Fare paid was $4300 for both of us, was a good deal, plus all the QFF J points, bonus points (5,000) and Status points for both of us (wife SS me SG) very handy. Half the FF points and bonus have arrived already!. Previous trip 2 years ago SYD/HNL/SYD was QA old plane expensive, not recommended.
Only drawback was that very old Q lounge in middle of nowhere at HNL, not been upgraded in years, the staircase to the lounge was filthy, basically stayed 15 mins and left.
