Saudi Arabia has a plan to build a huge airport. Saudi's Crown Prince told journalists about the plan. He said his country would change Saudi's current airport into a world-beating six-runway hub. The airport will be able to accept 120 million travellers by 2030. He hopes the airport will change travel in the region. It will be the world's fifth biggest logistics hub. The airport will also boost Saudi Arabia's economy. Another big plan is to start a second national airline - Riyadh International Airlines. This will compete with regional rivals Qatar Airways and the UAE carrier Emirates.

The Saudi Press Agency said the new airport would stretch over 57 square kilometres. It said: "The airport project is part of Saudi Arabia's vision to transform Riyadh to be among the top ten city economies in the world. It will help Riyadh's population grow to 15–20 million people by 2030." The new airport will be one of the greenest in the world. It will be totally sustainable. It will also be based on cutting-edge, green designs. In addition, it will be powered by renewable energy. A project spokesperson said the hub would be more than an airport; it would be an "aerotropolis".
