It seems the AW139 is stuck in China so they will be initially using a 6 seater AW109SP
From their Facebook...
“Our new service is launching on 17th March 2020, despite a delay to the arrival of the new AW139 helicopter, caused by current Chinese export restrictions linked to Coronavirus control measures!
Despite these unforeseen delays, our scheduled flights will commence in one of our VIP AW109SP GrandNew helicopters! 🚁“
