In addition to irishguy28's answer, it is worth noting that FB has moved away from single rate classic awards to enter a confusing world of multi band awards just like DL's. One of the difference between trying to redeem on 'your' programme (SM for DL, FB for AF or KL, etc) and trying to redeem on a programme's partner (use SM miles to book AF, use FB miles to book DL, etc) is that you can only access the non-lowest bands on your 'home' airlines. That means that a DL SM member won't be able to access the AF award seats NOT prices at the lowest level and conversely an AF FB member won't be able to access the DL awards that are not at the lowest level.
