Both
SeatGuru and
SeatMaestro quote the seat pitch of SAS A320s as 31-32" (and width 18"). This seems relatively generous in comparison to many European shorthaul aircraft (e.g.
BA A319 with 29" pitch and 17" width).
However, I can't find anything "official" on the SAS website to back this up (as far as I can tell, there's almost nothing about the shorthaul aircraft on there). In addition, I believe there's still some difference between business/"plus" & economy/"go" - given that's no reflected on the third party seat plans I'm wary as to its accuracy.
For reference, I'm looking at the LHR-CPH route - on the dates I'm flying BA and SAS are similar prices. I'm trying to decide which carrier give the best deal in economy. I'm a Star Alliance gold, so will probably go with SAS all things being equal.
If anyone has any experience with SAS A320 seats and/or can point me to something official, it'd be great to hear about it.
