Airbus is working on getting a new higher density version of the A220-300 certified. This will happen thanks to an extra set of exits over the wings, and it’ll boost the plane’s maximum capacity from 149 seats to 160 seats.
I'm summary:
- Cram 2 more rows in
- Add extra emergency door over wing
- Add extra flight attendant
- Tilt seats from 30" to 28"
