I very much prefer the 3 class 777 if flying Club World. I find the 2 smaller cabins are vastly preferable to the single large cabin in the 4 class.

Also I don't believe (speaking under correction) that either of the two LGW based 4-class 777s have AVOD.

Finally the fact that BA 2152 lands at 10am means you avoid the rush hour traffic if you plan to venture on the M25 ^ towards London. Not applicable in your case I know, but certainly helpful to me.

On balance I would only use BA 2154 these days if I'm travelling F.
