Getting a good angle on jets lined up on the approach is a combination of luck with where you can stand and the timing of the arrivals to be in sequence when you can get them all together.  It is also a question of whether you have the right focal length to catch them together but not so much that one is out of frame.  I played with this a bit at YVR.  Sometimes there would be a jet on the parallel approach too but combining the lot was more luck than judgement.
