What are good flight levels for these four routes....

I originally posted this thread in the screenshot forum by accident and it obviously didn't get many replies and ended up being deleted (which is fine, it was my mistake that I posted it there).So here it goes.What flight levels would you all recommend for these four routes for an MEA AI flight plan I'm making:Beirut (BEY) - Larnaca (LCA): 129 miles great circle routeBeirut (BEY) - Amman (AMM): 147 miles great circle routeBeirut (BEY) - Cairo (CAI): 350 miles great circle routeRome Fiumicino (FCO) - Milan Malpensa (MXP): 318 miles great circle routeAll routes would be flown on an A321.I was thinking FL210 for both Larnaca (LCA) and Amman (AMM) and FL300 for both Cairo (CAI) and Rome/Milan.Any help would be greatly appreciated! I want to have descent flight levels so the AI aircraft don't do a kamikaze descent when it's time for landing. :)Regards
