On my 2 F bookings (LHR-SEA and YVR-LHR), both on a B747, the new layout is different.

LHR-SEA shows the usual F seat layout, however, YVR-LHR shows the same seat layout but with the addition of Galley and Toilet symbols behind Row 5.

I can't understand why they would be different. OR - is this an indication of Old First / New First.

If I knew how to add images to a post, I would put the screen shots on.
