how I can take best airlines from saudI arabia Riyadh city to Jinan ?

To use the shortest travel time, you can fly to HK first and then transfer to another flight to QD. On the way, you are recommended to use Cathay Pacific Airways and (or) Deutsche Lufthansa.

If you wanna save money, upon getting to HK, you can go to Guangzhou or Shenzhen to transfer to a domestic flight to your destination, because the flights from HK to mainland China are regarded as international travel.
