The reason for the daily debacle with the BA 757 services through NCL whereby pax need to be transferred through a tiny door from the international to domestic section of the pier is that BA advised NCL there would be no more 757 services a while ago. Stand 3 was remarked for A320 max, then BA changed their mind...!
The 757 always used to park on stand 3 with no problems - there's even a picture of it up on the wall in gate 4.
