Unless BA siphons off high yield front cabin customers -- its J/C cabins are twice the size of AC's -- from AC, it's unlikely since AC seems to be able to sell out the cabin with full J or at least C most days, not to mention the late return from LHR.

I guess BA has redeployed its fleet to routes where there's a better business yield. However, is this not just a resked of the two seasonal dailies, or is it a third semi-daily?

Having arrived by Concorde at LHR around 9:30p, the place is pretty deserted with few onward flights, even to European cities.
