I'm a new member and I don't know if this has been discussed before, but I was wondering if there are any hard & fast rules that the individual airlines have as to displaying the mfgr's logos, and a/c type on their planes. I have been looking at photos on a.net extensively, and can't come up with a common theme. Some label all their aircraft, some - none of them, and some - intermittently.
At first, I thought it might have been when a new CEO takes over at the helm and wants to make subtle changes to mark his tenure. Then, I thought maybe it was when an airline changed color schemes, or that Boeing, Airbus, etc., coerced their customers into letting them put it on as a form of free advertising.
I know that there are many very bright and knowledgeable enthusiasts out there, as I've read your posts for the past few months, so any answers would be appreciated.
P.S. Do you think all aircraft should be marked?
