Affiliate Marketing Secrets

I am trying to fight my way through the CPL route and will start with my PPL. I have received application forms for a £10k career development loan but am unable to find any flight schools that are linked with this. Please can anyone advise me on any flight schools that are affiliated with the SFA for the ppl?
Thanks in advance

“Your flight is not guaranteed to be on one of these airlines. In addition, your flight may be booked on an affiliate partner of a participating Priceline airline (‘codeshare’) where one airline tickets the flight and enters into a contract of carriage with the customer, but another airline operates it”. what does it mean?

I am looking into being a travel affiliate I am wondering is 3% good? I have a website that has to do with Travel information so I thought adding some ads and banners to promote some Travel packages would be nice but I am not sure. I have been looking into it and it said 3% is that good? Because for example a flight can be between maybe anywhere in most causes from 500 and higher.

I recently booked a flight to China from the US through Orbitz. I was looking at my record number and it lists a record locator for Air China, when my flight itinerary says that I am flying China Southern. Anyone know if I got screwed over, or if they are affiliated?
