The A220s are now advertised with 30" pitch, although they haven't changed anything on those planes, so they maybe they have some 30" rows and some 31" rows?
Yes. Somebody here had shared an internal cad drawing, some rows are indeed have more pitch than the others usually +/- an inch, even seat width can be varied +/- 0.5" on some models.
