Thanks VintageKrug and others. I can see the availability when I just try to redeem my miles but as soon as I try and use my companion voucher it states “Select another route”. They are clearly blocking this on the CPT and other very profitable routes! This is extremely frustrating and in my view very misleading by BA who promote the companion voucher as a major benefit. I have family in CPT and have been spending lots on the AmEx voucher to boost my miles and to get the companion voucher – if the route to CPT is blocked (which it clearly is for the companion voucher) then in my view this is mis-selling and I would love to speak to senior management at BA about how they justify this. I am a frequent business traveller on BA and this just alienates a once loyal customer!
