How to delete multiple edge loops?

To delete an edge loop one can use X followed by Edge Loop. But how about deleting multiple loops at once?

I don’t believe there is a way, in 2.49 I would delete a section of edge loops by selecting them. And then using the F, bridge faces. I’m not sure if this is in the current blender 2.5 version yet. Haven’t beenusing blender much lately.

Good question. and why does it create triangles sometimes when I delete a loop?

That’s probably because polygon subdivision is not even on both sides of the edge loop, so Blender has to compensate by drawing a triangle. But I really don’t see a solution for deleting multiple edge loops, this is something other softwares do very easily, even on multiple edge loops selected in different patterns.
