First step I recognised the prop. THerefore it was either a Saab, an ATP, a J-31/41 or an Il-114.
Step two: two cheatlines above eachother. My guess was that you would post a UK airline since those are easiest for you to shoot. Only Eastern fits that description.
Step three: AJJ could easily be read. MAJJ is a plane I once spotted before (still in BA landor back then!) so I had all the information handy.
Damn, you’re good!
