I think the dual fleet complexity will be minimized and made up for with the operational advantages each airframe provides. Apparently Neeleman thinks so too. Makes sense for their intended business model where they can take advantage of both high and low utilization route structures. But I agree, 2 fleets is always more complex than 1.

I think the pay scales are fairly similar, less than $20 difference in the left seat between the two planes, even less difference in the right. And I don’t think the long seat lock applies until after you switch off your initial air frame. Also, there are some nice things about being on the 190/195...like being home every night, being in a smaller base in an area you may want to be where the 220 isn’t based, and working bankers hours, which may not be the case on the 220. Regardless, there should be an opportunity to pick your poison at some point.
