Again, if they are engaging in a huge repainting scheme, managment should be hung out to dry. No need spending money on something that is non-essential. If its only going to be applied to new deliveries, then its not so bad. Of course, with the rate at which NW retires airplanes, they would have their entire fleet in the new logo by 2035 or so.
Having said that, I would also think that changing their name from "Northwest" to "NWA" will have many passengers, particularly in non-hub locations saying, "Who?"
Dropping "Orient" from the name, which a lot of folks probably did not say anyway, isn''t so bad. Same for Midwest dropping "Express", especially with the connection of "Express" to many regional feed operations. But "NWA" does not roll of the tounge like "Northwest", and why change when passengers already know you?
