Which country now has two airlines - both as national flag carriers

Saudi Arabia has unveiled a new national airline.

To Middle Eastern powerhouses Emirates, Etihad, Saudia, Qatar Airways and Oman Air add newcomer Riyadh Air.

The new airline will be led by CEO Tony Douglas, an ex-Etihad executive, and is wholly owned by sovereign wealth fund PIF.

The Saudi airline is aiming to operate to more than 1000 destinations by 2030, Travel Mole reports.

It is predicted that Riyadh Air will generate up to $US20 billion for Saudi Arabia’s non-oil GDP growth through tourism and trade, state news agency SPA said.

The airline will be based at Riyadh’s King Khalid International Airport.

Saudi Arabia’s Crown Prince Mohammed bin Salman announced the new carrier, which will operate alongside head of state-owned Saudia while serving different destinations.

Saudi Arabia is now home to two national airlines, both serving as the kingdom's flag carriers.
