It's axiomatic that pay is inversely proportional to fun when it comes to professional flying. Since leaving the military I've done long haul pax, long haul freight and short haul pax in that order. I can't say any of it has been much fun. The only flying I have enjoyed since the RAF is when I've paid to strap an aerobatic aircraft on my back and let rip.
So it would have to be back to ther RAF for me - probably instructing.
