PR operate narrowbodies SYD-MNL which is a bit over 8 hours. I was VERY glad to see the flights I needed in November were going to be on the A330 instead.... The seats may be the same (PR's long haul narrowbodies actually have lie flats in J, not that Im flying up front this time.... lol) but the general feeling of space and aisle access are two things I really like about widebodies.
