The MEB3wil l be after the transfer traffic that currently transits LHR and AMS in particular
Not sure given KLM don't serve BFS-AMS or Air France to CDG, or Lufthansa to FRA, there's a whole lot to mop up to be frank. (not fairdealfrank clearly)
BFS is becoming to DUB what BHX is to LHR, it's just easier to hub there.
