Hi I have an activity ending in late June, and I was thinking that I might end it with style. I thought that I might do som kind of "leg run" and visit three capitals (or at least the airports) at one day. I was thinking of ARN, CPH and OSL in som way and I was wondering if you guys knows how to find the really cheap tickets. It takes som time to enter all alternatives one by one in SAS booking tool... I found tickets for around 600 SEK for some flights. When are the flights cheapest? Weekends, weekdays, early, late, mid day?
