Filmed over the last

18 months, we follow passengers trickling back into an airport dealing with ever-changing challenges.

Passenger Service Manager Demi, above, is tasked with helping confused passengers, including one granny-to-be who has been turned away from her flight because by the time she gets to Zambia to meet her new grandchild – her Covid test will have expired so she can’t travel.
