The issue is that points arising from business travel might be a "fringe benefit" and therefore your employer - not QF, not you - would be required to pay the FB Tax. OK, not your problem unless your employer "avoids" the FB Tax by asking QF to withold FF points on business travel!! Points that are not completely transferable are less likely to be held to be a benefit. For similar reasons QF won't sell points - because to do so would help the tax office to place a value upon them.
