Processes for making aviation fuels include a step of forming a C16− olefin stream by oligomerizing a mixture of decenes with a C6− alpha-olefin or by subjecting the mixture of decenes and a C8− alpha-olefin to metathesis. The C16− olefin stream is then hydrogenated to form C16− paraffins, and these C16− paraffins can be used to form an aviation fuel. Particular C11-C16 olefin compositions and paraffin compositions prepared by these processes also are described.
