FormerlyDoS, no I haven’t. The only time I travelled with a companion on BA I elected upper deck 64A and 64B. I would prefer that whoever sat next to me in this configuration was someone I know 🙂 so I see a point with this. One could argue, that the newish LH offer where you seem to play footsie with your neighbour offer a similar challenge.
On a side note; I wish you plan to stay in the forum as a contributor. Would be sad to see you go.
