from what i've seen, it's not like regular funds transfer na account-to-account. ateneo is listed as a merchant, which means you can pay your ateneo bills through bpiexpressonline. pay bills and not fund-transfer.
i have an expressonline account and i tried the ff based on the suggestions given in the website: in your expressonline page, find bills payment > enroll all other bills (or something to that extent...di yan ang exact words nila) and naka list under merchants/establishments ang ateneo de manila - loyola schools. i haven't figured out what to do after that
