Hi Ryan93,
I spoke to someone who wasn't dealing with the BA scheme directly but they said the invitations should have been sent out by now. The "thanks but no thanks" emails should be sent out soon apparently. Then again this person isn't directly involved with the BAFPP so things may be different. A bit like wedding invitations, if someone can't make it you send the invite to the next best option!
I haven't had any emails however since submitting the application.
