I don't think any airline scheme guarantees you a job afterwards... of course your chances are far greater.
I think the BA FPP will run again as the risk is taken by the student and not BA. I also remember them wanting the actual grades but could be mistaken by that. (Pretty sure someone asked that on the FPP thread a few weeks ago).
Get a job and start saving. Go and visit potential schools to see what you think
Nice results by the way
Buena suerte
