GA+ offerings, as opposed to pure corporate (who will spend the money much more freely), have to be really compelling for people to shell out for them. Yeah, they're expensive, but if people feeling they're really 'special' they'll consider them for special occasions etc etc.
All of which is fine, but in all the coverage I have seen of the options, in terms of what you actually get for the cash, the pricing looks way over the top.
I saw the VoT youtube of one of the cheaper offerings and thought, yeah, looks nice, but for several hundred quid for some really average looking food, two drinks and a gift of a mug in a box, it just looked more than a bit shit.
it doesn't look 'special' to start with, which is just the first problem.
