Agree, but there may well be a further complication if even a small proportion of the travelling public can't or won't distinguish between the 737 Max and the thousands of others without the particular model suffix. Very difficult to predict or quantify but it's difficult to believe that there won't be some collateral damage to the 737 brand. I imagine the
PR and Commercial departments of "old" model 737s will be giving this some thought and will be looking for any signs of avoidance.
