This is just great!!
If family members can fly together and are on a good interpersonal basis then the chemistry must make for a good flight deck environment. If things are tense I am sure they would have the sense to desynchronise blocks.
When times are good it can only be good and harmonious for the airline.
Go families!!!
It is something inside - and shared it is multiplied.
God - I am sounding like a bloody Mormon.
Best all
