Guys,
I think this is purely a training capacity problem. BA are hedging their bets, IMHO, in order to free up the Airbus training capacity for the integration of BMI, if approved.
All BMI crews will require a differences course plus an LPC/OPC. Admittedly, probably a short course, but with 300+ to get through AND the normal line checks for BA crews, it's going to be a very busy time for the trainers.
Within all that fitting the DEP courses in would be a nightmare.
Obviously just musings of mine but that is what I make of the picture.
The DEP's are still required but there is no training space for them for the short term. It all hinges on the approval for the BMI integration which we will know fairly soon.
Just keep swimming!
