Funny that. I emailed AA just over a week ago and their email reply flatly refuted any IOM-LTN operation, although they said it might be someting they would look at next summer.
As LGS has stated, the BACX is likely to be killed off by this move. Obviously LTN management have tried to prempt any move of BACX withdrawing the route which has been on the cards for some time now,with AA now a willing source.
