There is some truth in this rumour. Some representations are rumoured to have been made to the management in recent days. These requests were not dealt with properly - the managament should have said a very firm no! The numbers quoted have varied but it could involve up to 6 Captains and an unspecified number of FOs.
The bottom line is that there are a number of promotable FOs at GB who have patiently waited their turn on the seniority list. As long as that situation exists, direct entry commands would be totally unacceptable to the pilot population at GB, particularly the FOs. There is no doubt that such a move, if presented to the CC, would be immediately rejected. There are no circumcstances where such a move would ever be acceptable, and would almost certainly result in industrial action.
