TPP, you said it, mate! But well done for apologising to your peers - a brave move.
As for the future, don't give up on BA yet. As I understand it, they've placed you in a hold pool so that they can resurrect your training courses as soon as they can see further ahead than the end of their nose - not easy at the moment. That, obviously, leaves you in suspended animation with no information. There can't be any information until BA, and everyone else, has some idea of how the aviation world is going to shape up in the medium term. That cannot be determined with any hope of accuracy until the military action is long over and passengers start to return to the airlines. Let's hope that's sooner rather than later!
