That, surely, has to make their experience different, no matter how hard I try with those I "don't know". Maybe that's where the smaller airlines have the advantage.
I think that this is an insighful comment from JSL.
With regards to Air Malta, I don't know all the crew (but do know a substantial number) and when we do know each other, the experience is different as they can judge from my body language as to whether I am tired or not, whether I am working or not etc.
Intuitively they can deliver a good service as they have an insight into my patterns of behaviour and expectations.
Also, Mediterranean people are, by culture, relationship focused and this is noticeable.
The smaller airlines (or regional units of the biggies) do have an advantage in this respect.
