Irish Carrots - as I suggested earlier to WestonFlyer why not actually pop in to NFC and ask all the questions you need answers for. As for their record you can ask the CFI for a list of students who have been taken by the airlines.
Both AFTA and NFC offer quality products - AFTA scores with the contracts for airlines and therefore the volume/throughput is bigger which is where you will suffer as a self funding integrated student as you'll fall down the pecking order when 'contract' deadlines loom. Percentage wise, I'd be surprised is there was a vast difference in FTP rates or placement outside those contracts
