767 morphed into Mid Fleet with crew operating 757 and a small number of 747 routes - more upset!
And also the 777 which eventually made up a lot of the work.
There was also an Airbus division on NBA (Shorthaul) which was well loved by the crews and not to forget the elite Concorde crew who had their own work group! Now that fleet really was considered 'outstanding'.
Then at LGW you could say that 'Airtours' crew (charter and scheduled holiday flights) were a separate fleet until they were merged with BCal to make BA LGW.
On long-haul now there are 3 divisions, and only one of those (A fleet) has three licences 747, 767, 777, the other two don't have 767. They may well be in the frame when the A380 comes as they can take it on.
