I've got one thing: The interlinking of luggage on separate bookings is back! Confirmed as working 30min ago when SAS-ARN checked my bags for ARN-LHR-SIN-SYD. This saves me so much hassle at LHR. Also, on a day like this, I made sure the lady at the desk understood how much I appreciate this, and I believe it's a great service from SAS.
