"simply because El Al"
Does El Al have specific detection equipment in any airport from which planes flies to Israel, and vet anybody in those airports?
I'm quite sure it near to impossible to board a bomb in Tel Aviv where they have full control, but what about planes flying to Tel Aviv? Sure, they may undergo some higher standards, but, still, they are airports not under their control.
And how many Emirates airplanes were ever attacked? Terrorists may have several reasons too to avoid them, and the security of those airport is not the same of the African airport where the last bomb was boarded. I'm sure in some African airports you can try to board an elephant, and with proper bribes achieve it.
