Names for aircraft, often with a fleet "theme", do seem to come and go with operators over time. Since the advent of jetways, with few pax now seeing the nose of the aircraft, they do seem to have a limited function.
Another aspect is they do not seem to last, almost all which get applied end up being changed or removed long before the aircraft is finally sold. BA had several goes with different name patterns on the same aircraft in its fleet, others have done the same. Even Pan Am, which used its "Clipper" name sequence through to the end, used to cycle them round rather than leave them be.
