Saudi Arabia will build a big airport. It will have six runways. Over 120 million travellers will use it by 2030. The airport will change travel in the region. It will also increase Saudi's economy. Another big plan is to start a second national airline. This will compete with regional rivals Qatar Airways and the UAE airline Emirates.

The new airport will cover 57 square kilometres. A spokesperson said it is part of Saudi Arabia's vision "to transform Riyadh to be among the top ten city economies in the world". The new airport will be green and sustainable. Planners made cutting-edge designs for it. It will be powered by renewable energy.
