While it is a tempting thing to do by listing twice on the same flight this is against the terms and conditions of staff travel. As it is perfectly possible to book a ticket on staff travel up until the flight closes then there isn't really any need to do this.

While getting the Club seat, especially on long haul is a great potential benefit of the premium standby, in actual fact the benefit of 2x32kg instead of 1x23kg is normally worth the extra fare component if you need the extra luggage.

Breaking the terms and conditions of staff travel can and does result in the withdrawal of staff travel to individuals, so it's not really worth tying to bend the rules.
