Joe Public can't tell what airline you are any way.
How many times have you smiled, given the knowing nod to a pair of pilots from another airline walking the other way and thought I have no idea who they work for.
So if we (pilots) can't tell then the pax sure as beans can't either.
Even if we walk with our crew (Which doesn't happen often).
The pax don't give a rats, all they care about is price and making it to the other end alive.
What a waste of money... Well done EK
