Hi DawnChrus01,
You have not missed anything if you have attended the first session on 09 August. However, now there are 70 places instead of 60. Which is good. The recruiters have not confirmed eligibility queries related to non-UK citizens or permanent residents.
Additionally, you can not live at your home while under training as BA will have paid the cost of accommodation and food to the chosen flight school.
Besides, if you have previous flying experience, then the Head of the Flight Training School will decide on how much reduction in flight training will be allowed.
I hope this helps you and other on the forum.
