From this forum and another, the people who have said they have a training course for january all have previous flying experience and noone without or may be ex-employs of BA?! Also those with assessments in July have been offered a place before those who had assessments in April :-S Sorry its just an assumptions though. You say you also have flying experience - Im guessing there are many of you that have and hence they are cherry picking at the moment and assessment date order has gone out the window.
