United Airlines is canceling it’s Newark (EWR) to Mumabi, India (BOM) route due to a recent ban placed on flights over the country of Iran as well as the Gulf of Oman and Strait of Hormuz.

This ultra long 15 hour nonstop flight between Newark and Mumbai is only possible with the ability to cross over Iranian airspace. Pakistan is situated next to Iran, however, their country also has a no-fly restriction at the moment due to tensions between India and Pakistan. Another alternative route would take the aircraft too close to Syria and Iraq. With no other viable alternative without adding a refueling stop, the decision was made to close the route altogether for the time being.

Airlines try to avoid fuel stops whenever possible due to the delay it could cause the flight, as well as the additional costs incurred by the airline and reduction in potential profits on the flight.

The United Airlines route between Newark and Mumbai is an important link, as Mumbai serves as the financial hub of India. The route typically carries businessmen and wealthier passengers. It’s a safe bet that United Airlines will resume the flight once tensions with Iran cool down, or the situation with Pakistan improves.

Until that time, passengers will need to connect through Europe to reach their Indian destination.
