I am planning on going to SA a couple of times over the next few months. How is the ride in FC and Coach? I am a NWA elite and plan to upgrade to FC using miles but want to make sure it is worth it.

Last year I did Rome to AMS and did not get good service in FC.

I undersatnd this flight is much longer but is it worth it? Is the food/service that much better? is coach usually 3/4 of more full?

TIA
