If you look on Google you can find an interview with Neeleman from a year or two ago discussing how 20 of the A220s will be a yet-to-be-announced LR version with 4,000nm range with an ACT (I’ll try to find the article). I think he mentioned Europe, Deep South, and Hawaii in that article (or maybe it was somewhere else).
