2-4-1 – UK to South Africa – a few questions

Hi,

Thanks in advance for your help/advice.

I will soon receive my 2-4-1 voucher for BA, myself and my other half are hoping to visit friends in South Africa in the next 6 months/1 year. We have over 300k Avios so hoping that this will be enough, along with the voucher to travel either Business or 1st Class.

My questions are:

Is it possible to fly using a 2-4-1 voucher from Manchester to Johannesburg, the return journey would likely be from Cape Town to Manchester?

We are likely to take a few internal flights whilst we are there so if I were to book these when making the original booking could it be done using 2-4-1 ( in business or first) or is this not possible?

I’ve had a quick look at the prices to Johannesburg, just to give me an idea of prices of taxes etc, some flights it looks more expensive to book Business Class, does this translate into the number of Avios required?

When we’re ready to book is it best to ring up BA to sort out the flights rather than online? We can be fairly flexible with dates so I thought that it might be easier to talk to someone whist sorting flights out?

I know that there are a lot of articles on this website but there seems to be lots of rules to follow and I think I could probably get things wrong. I’ve never used the vouchers before and I would like to try and maximise our use of the voucher whilst using least Avios so that we still have enough to plan for our next trip.

Thanks in advance
