"Boeing appears to have started quietly dropping the “Max” from its 737 Max aircraft in the wake of
recent air disasters, instead referring to a 737-8.
The new name has hitherto been used only internally at Boeing and emerged when the company put out a
statement on Wednesday to announce it had won its first order for the grounded 737 Max aircraft this year. Poland’s Enter Air SA agreed to buy up to four variants of the jet."
