Nick, what Mont is saying is that they probably won't be of the standard Jetphotos are perhaps looking for. Click this link below which are some of mine and see the difference. Then you will know what the Jetphotos screeners are looking for.

You definately have a camera capable of taking quality shots which could be accepted on Jetphotos, just looks like you need some help sorting out how to use the camera best. If you ever wanna hang out at the Airport I'd be happy to spend some time with you to help you bring them up to scratch, I am normally there every Saturday and Sunday. I am no expert I have only recently started submitting to Jetphotos myself but I am happy to help if I can.
