SAS and Thai had a DC-8 interchange/leasing arrangement for many years so it's possible pics of a Thai DC-8 might actually be a SAS aircraft operating SAS flights.
Interesting news on VS. LAX for SFO is a straight swap by the looks of it (now that the A330-200s can get to LAX which the -300s I doubt could) but that is some serious capacity growth on ATL and JFK with 450 seats a day to each.
