Need some help/advice from all you fine folks who've done this before.

Trying to find a cheap way to get from Oslo to Paris in late August. Me, my wife, her sister, and her sister's fiancé will be traveling around Europe for about 2 weeks, and that's one of the "legs" of the journey. Won't be able to use ZED or discount types with the airlines.

Thanks in advance. Look forward to hearing from all of you with experience here.

If this isn't in the right forum I apologize.
