I've built up a substantial (well substantial for me) amount of Avios and I'm wanting to book return flights for two to South Africa having never been. I'm looking at going November/Decemeber 2019 so am aware I can't book as of yet just trying to be organised as I know CPT can be especially tricky. I should also mention I have both a Lloyds Upgrade Voucher and a BA Amex 2 for 1 voucher. Having priced up out in F back in J with BA the taxes are well over £1200. So I was just wondering are there any clever tricks for reward bookings to SA. As from what I can see QR is waste of time as its peak price and cost of two long haul flights. Does booking with IB from Madrid save anything? Or should I just stop being tight pay the £1200 and see it as good use of the voucher.
