quality
The quality comes from the product hard and soft and how it is delivered.
With a lot of brand new crew they can be trained accordingly there will be a bedding in period. I know that at LGW the service still doesnt run as smoothly as it should at times.
But balance this on my recent experiences with so called `veteran` crews. The same applied in a way in that the delivery of the service was sketchy at best, I presume also new crew will allow the concept of `premium crew ` to be developed.
So overall the quality experience will be preserved hopefully. No reason why it shouldnt be monitored for the new crew.
I also guarantee the new crews will stay well in excess of 3 years, there may be a higher level of attrition as at LGW but the company are happy with that scenario.
