Try travelling out of Lagos airport a few times, and trust me, you'll find that a VS gold card is one of the most useful things to have in your pocket.
Instead of a 1-2 hour chaotic check in, just go to the upper class desk (even if flying economy), and you're through in 10 minutes. Then it's straight to the lounge, instead of sweating your nuts off, waiting in temperatures that would be good in a sauna.
