Route 400 of the Madinah Bus project continues to carry passengers between Prince Mohammad bin Abdulaziz International Airport and the Prophet's Mosque as part of public transport services for visitors and Umrah performers.

According to the Madinah Region Development Authority, the route runs 24 hours a day, so passengers can travel easily between the airport and the mosque at any time.

The service gives new arrivals a direct connection from the airport to the central area, making it easier to reach the Prophet's Mosque and to get to and from the airport.

It forms part of Madinah's public transport network, which is designed to offer convenient travel options for residents, visitors and Umrah performers.
