There is an article in Ekstra Bladet today (In Danish) aug 19, about how the ticket price may vary a lot depending on what SAS country homepage you order your ticket from.
As an example you could save 20% on a return CPH-BRU, if your order the e-ticket from the SAS Belgium homepage instead of the Danish. An on-line ticket CPH-BRU bought on the SAS DK homepage might cost 1192dkr - if you order it from the Belgium homesite the price for the same booking would be 996 kr.
So if you are going to some destination, it might be worth checking out the price difference.
If you are wondering how you can access the different country homepages, just click the SAS ikon, and the country list pops up.
