Just booked my biz class flight from LHR to IAD Oct 2025.

Does anyone know if this route is the new retro fitted 788 CS seating of 1:2:1 or the same 2:3:2 configuration???

Flying with my wife, usually we're on the A380 and sit in the middle / couples seats. What is a comparable seating arrangement for couples in CS biz section on the 788??
