Hello All!

I'm new to the forum but have been lurking for a while. Hope this question is in the right place as it applies to a lot of different airlines...

I am looking to fly 2 x family members from London to Cape Town for Christmas (around 16 Dec to 26 Dec). As you can imagine, this is a very expensive time to be doing this! Cheapest sensible fares I can find are about GBP930 per person in economy.

I'm trying to come up with a cunning way of reducing the bill by identifying a suitable reward program, wracking up some miles and getting a redemption. Over past 12 months I have accumulated about 350,000 Avios mainly through Amex credit card churn and Tesco Clubcard offers. However, British Airways do not have much availability, so am looking to other airlines. In particular:

Air France
Edelweiss Air
Ethiopian Airlines
Eurowings / SunExpress Deutschland
Kenya Airways
KLM
Lufthansa
Qatar
South African Airlines
Thomas Cook
Turkish Airlines

Anyone have any ideas on credit cards I could direct spend through or mileage purchase offers I should look to? I already have an Amex Platinum, BA Amex and Hilton Honors VISA.

Any advice would be much appreciated!
