It's been a month since Saudi Arabia opened its airspace to flights by companies from Israel and the similarly necessary approval from neighboring Oman has not yet arrived. It is possible that this confirmation will arrive in the coming days, but the delay is not accidental.
The ties between Oman and Iran are close and have only gotten tighter in recent months. Therefore, it cannot be ruled out that there is pressure from Iran on the Sultanate not to open skies to Israelis. Trade relations between Oman and Iran are only getting stronger.
The last quarter, Iranian exports to Oman jumped by 123% and amounted to $415 millions. In addition, in the Gulf there is sharp criticism of Oman for allowing the pro-Iranian Houthis in Yemen to use the Sultanate to smuggle weapons and money. Oman does not define the Houthis as a terrorist organization.
