The woman on the plane...

...does anyone know the name of the woman who played her? I'm just curious, because, as often happens with British films like this, I suddenly see people all over the shop who I recognise, but can't remember or don't know the names of.

This particular woman was in an episode of Peep Show - she was a student at "Dartmouth" (I think) University, and was in Mark's hastily-adopted-and-very-temporary history class.
