First class vs business class on A380 is it worth it?
Agree with JackieD if you can upgrade a single sector that would be best value. Having travelled alot in f and J in the a380 my view is that F is a very relaxing way to travel. Meals on demand and close attention of crew vs J. I find that I tend to "waste" my F time as I spend most of the flight at the bar! So if you intend to mainly sleep, eat abit and use the bar then probably J best. If you tend to spend most of your time at your seat then go for F. It is a step up from J no doubt and the shower on a long flight can be quite refreshing. Personally I would use the 10k to get a better room / suite at the hotel but that is only because I tend not to sit at my seat much on the flight!
