I see that you are unhappy at BA, and would either like to move on, or regret leaving your previous employer, or both?
It might be useful for those here, waiting to join BA, if you tell them where you aspire to be now? I'm sure it would prevent them wasting their time in the hold pool, if you could give them the benefit of your experiences.
Alternatively, where did your 'due diligence' fail, prior to both applying, and then committing to BA?
Rather than telling them what's 'wrong' with BA, how much more helpful to just say where the entirety is better?
