SAS
When I did the flights last weekend they were selling the Economy+, so I would think you would get lounge access.
The flight is very popular with both UK pax and Scandinavians and it looks like a 50/50 split. Both my flights were full. OK there are only 2 a week on a 736, but as I mentioned before SAS are really pleased with how well the flight has sold. It should be extended to a longer operating period next year, with hopefully a larger aircraft.
With this, you would hope that someone like LH would get wind of how well this is selling, without the connecting traffic and get something going themselves!
