then isn't it immoral to take advantage of $27 flights to paris (or other associated $0 fares)? they are obviously a mistake, a loophole if you will, yet there is a "list" devoted to such mistakes. does that make "the list" immoral as well?
(i'm glad we're having a morality/ethics discussion so close to christmas. it makes good sense to examine what types of individuals we are at this time of year!)
cheers
