Good god, are you mad? Yes, it is closer to the bar, but it will take you ages to disembark behind all those other seats. For whatever reason, there's always a lot of old people flying EK J and they are very slow to get off. Disembarkation time on an A380 is critical because there is a floor below you who are just waiting to choke up the immigration queue. If you want to go to the bar, walk the aisle mid-flight when you are not racing to beat the grey nomads off the plane.
When I am slumming it in J, the only acceptable seat for me is 9A. 7A is too close to the galley and 8A is an aisle seat so you have the work-experience crew brushing past you all the time. And don't get me started on K... that adds an extra 30 seconds to disembarkation. So, 9A it is!
Nah, the real frequent flyers grab the F-Saver deals and are safely ensconced up the front. If they do venture to the bar, you'll be able to identify them because one of the F attendants will come down with some real bottles of grog just for them.
Remember to ask for an Express Arrivals card. They often don't give them out, and even if you ask, they will often tell you that AKL does not have an express lane. It bloody well does! However, if you sit in 9A, you'll won't need the express lane because there will be no queue at the passport machines and you can go straight through.
