BMTA has about 15 buses for the service which operates daily during 4am-10pm. The estimated travel time is 90 minutes, excluding waiting time for the bus which might be 15-30 minutes depending on traffic.
Unfortunately, the bus isn't designed for passengers with large luggage. BMTA operates the service with a normal yellow air-conditioned bus. It plans to increase the number of buses to 20 within the next 30 days.
