From what I understand the fto's send a file for the top x candidates to BA. If there are 60 slots, then I imagine 80 are sent and the ones either side of 60 are discussed in detail. The lucky ones get invited for a free lunch at Waterside...
The reject list is passed back to the fto for them to pitch self sponsorship to.
If I was a betting man/woman (delete as appropriate) I would say the lucky ones will receive an invite Tomorrow or Monday.. The rejected people a day or so later..
