A green, silent bus idled at the park, outside the domestic arrival terminal of Nnamdi Azikiwe International Airport, with doors open and seats mostly empty.

A few metres away, taxi drivers called out for passengers while travellers wheeled their luggage past without a second glance—some heading for car hire services, some to their personal cars or family, others opening ride-hailing apps, and one of many passengers making her way toward the green shuttle bus.

Inside the bus, Anita Mathew sat waiting.

“Well, I am using the bus for the first time to try it out. They told me about it at the exit door, so I said let me try it,” she said, glancing at the bus door at intervals.

But even as she settled in, she was uncertain if she would return.
