There are no 767's at LGW at the moment and I haven't heard any rumours of a move - which means it'll probably be announced today
. Some tinkering happening with the 777 ( e.g. due to the dropping of the Sharm route) but I'm not sure what, if any effect that will have on the basing of the 777's. You certainly wouldn't be talking about moving many, if any, hulls.
