Bucksnet – if it was a 2-4-2 then like British Airways the people in the windiow and middle seats would end up needing to climb over the passenger on the aisle to get out. That isn’t the case.
Even BT indicates it is staggered 1-2-1 seating.
There seems to be a nasty whiff in the air at Krug towers these days. I’m surprised VB hasn’t wheeled out the usual list of quotes from down memory lane. Still maybe you can ask about the seating when grill Mr Walsh at the Taste of London.
