NEC ECC: Can the cost of overseas flights be recovered under people costs?

Under NEC4 Option A can the cost of overseas flights and living expenses be recovered under People Costs? The project is overseas and has been delayed and there are further CE’s to assess

By a strict interpretation of the contract, I think ‘No’ as these costs are not incurred “within the Working Areas” as per the last sentence of People in the Short Schedule of Cost Components.
