Good morning. I have a question about booking a business class ticket on SAS and I was hoping that someone might have some insight. When I get to the seat selection page, it shows two categories of seats that have an up-charge; there are plenty of these. The key also shows green seats, which are included in the price; there are none of these. Is there any way to book a seat without paying? It was over $100 per leg, which is not an insignificant increase to the overall price of the ticket. Any advice would be appreciated.
