Of course, none of us has flown the neo or the MAX, and neither do any of us understand the economics of the choice.
But, emotionally and physically, I clearly prefer the newer 320 planes to fly on over the newer 737s to fly on. Clearly, there's the cabin width, which will remain an advantage of the Airbus, but currently there seems to be a generally more modern feel to the interiors and the general experience - although I recognise that such may be down to the individual airlines.
Shame it's gone this way but I guess inevitable. I just hope we don't have to pay higher fares to pay for it.
