If you look at their FB page it seems SAS has gone into a slight meltdown in the last few days, it seems they are giving the Norwegian/DY customer service model we've seen the last few summers a run for their money.
It was bound to happen eventually, with the continous cost cutting and outsourcing. Usually the shorthaul fleet has not been the problem for SAS, but now it is high season for charter and sun destination travel and a lot of the domestic trunk routes are being plied with CRJ900 from Cityjet. Trouble is Cityjet has some 500 cancellations of SAS flight in May-Aug this year due to pilot shortage, so once those flights go belly up and all the mainline aicraft are in Spain, Italy, France etc there is no back-up. On top of that staff ground staff are usually outsourced, phone hours are limited and if you get someone they may well be in Lithuania or something because they are also outsourced.
Could be some interesting press stories for SAS this summer if they keep this up.
