I think this is just gonna irritate the freq flyer in Y class who paid $600.-$800. for a ticket and then has to cough up three bucks for a snack pack. Plus the cost of buying and stocking and serving the thing is probably more than then can make by selling it. Better off to just give it to everyone but keep it small and simple and inexpensive like in Europe where you pickup the ' snack bag' on the jetway when boarding the flt.
