I suggest you read through the dedicated thread linked above.
I did which is why I had more questions !!
If you can use the booking engine to book, and it prices in the local currency of departure, then why does there appear to be an issue with ex-SA fares ? .. the FAQ's also don't say who the ticket is actually with ? (Is it one airline - if so what determines it ?)
Sorry if being naive but just trying to understand the process before I look at itineraries in detail.
Thanks
