I agree for the most part. If I were flying UC one way, outbound would be UC over the inbound leg, even on a night flight. The CH lounge has to be the best start to any holiday. We used the Guest List when flying PE to NYC and though expensive, had such a great CH experience, we though it worth the money. So I would pay £50 to fly down for the CH experience too if i were living up North.
But as I said earler, would not bother for LGW in all liklihood.
