As someone who used to do logistics, I think most airlines who don’t already have A320 family aircraft will prefer the A220. But those with existing A320 family aircraft may well prefer the A319 NEO due to parts and training commonality with the other aircraft - NK as an example. If you already have typed pilots, sims, and spares suitable to a 319 NEO, the incremental cost of just going with the somewhat smaller and shorter ranged 220 may well offset the cheaper price tag. And list prices for new aircraft have always been written in smoke - even before COVID. And the fact that the 319 is on the same production line as the other 320s is a feature, not a glitch, for Airbus. They enjoy the same training, machinery, and parts economies as well as economy of scale.

And the upcoming stretch models of the 220 may cost as much as a 319NEO in any event. Time will tell.
