The whole selling point is – the certification program, such as it was, was based on – the idea that it’s “just another 737”. In due course the 737-dontcallitMAX will be recertified with some software bodge (perhaps I’m being unkind here?) and will be listed in flight schedules for the unsuspecting public as “737” – which it is, isn’t it? Ordinary Joe SLF won’t be able to tell whether he’s going to be on a classic 737 or a disguised MAX, especially as the exact equipment type may vary from day to day or depending on availability.
