Why or why not the 220 is a fair question, but everything from the company up to this point says that they’re not interested. It is a modern and efficient type, but it would also bring the significant cost of adding a type. I’d suspect that the max7 could cover the same markets without the expense of adding a new type, but they don’t seem interested in that either. It’s all about max9/10’s, 321’s, and upgauging. I thought that they would have added the 220, 190/195 E2, or max7 since the pandemic but they haven’t really expressed interest in altering the current plan.
