Nice one ! Maybe a bit long in the end when there are fewer aircraft landing a taking off in the distance. You might shorten it by 5 or 10 seconds ?
I did a test with handheld time lapse photo in the subway a while back, editing together different FPS versions. I should probably get back into it, it could be fun if I get enough footage to cut down.

Then there was a tripod time lapse I did a couple months back, wanted to have fun with the color.
