Forgive pax intrusion here:
....and finally the company adds a crew member and makes it a position that isn't required to assist us in delivering that service
A few months back I witnessed the Concierge helping on several occasions with the drinks service in Economy between LAX and AKL on NZ1.
She was also great with our kids and met us in baggage reclaim at AKL to point us in the right direction to the Domestic Terminal, as we had a fairly tight connection to CHC.
Pity that on the NZ39 return to the UK 3 weeks later not a black-suited lady or gent in sight.
