Really? I want to like the A220 as much as B6's E190, but can't because I can't get past having the middle seat and other reasons listed below. Almost every seat on the E190 (except bulkhead & last row, like all planes) is terrific. EMS seats are more spacious, but even the core seats are great on E190, IMO, making it *by far* the most comfortable Y seat available in USA.

While I get that the A220 will have better-designed overhead space (allowing for more bags), what other benefits does it have over the E190?

From what I've read in recent announcements, here are the quality drops in E190=>A220 on JetBlue:

1. Increase from 100 to 140 seats. It'll take longer to load/unload, get checked luggage...etc.
2. B6 version will have the awful & tiny SpaceFlex bathrooms(!) in rear. When announced B6 chose A220, I warned this could happen but everyone said Airbus wasn't configuring SpaceFlex on A220. So much for that!
3. Seat pitch will almost certainly be reduced, compared to E190 since that's happened on every new B6 config since all-core A321.
4. No middle seats on E190. There's a middle seat on A220 (and saying it's 1" wider doesn't offset that it's a middle seat)

I'm not questioning why B6 made the switch to A220...just questioning why customers (especially Jetblue loyalists) are excited for it.
