Thanks, and thanks for asking!
Definitely planned. I live in the suburbs of Atlanta, so I often watch for planes leaving the airport and crossing in front of the Moon. Sometimes I can go hours without a shot and other times I can get a few - it's actually a lot like fishing! It has also become an obsession of mine.
This plane wasn't from Atlanta and was travelling West to East at an high altitude. I saw it coming. I use an app called "Flight Radar 24" to identify planes, but this one didn't list where it was going. Shots of planes just passing over Atlanta are more rare, but I have caught a few.
I actually caught a second plane about 30 minutes later - not as cool a photo, but an interesting story. I didn't see it coming. I had just taken a photo of a wildflower in my yard and was re-focusing on the Moon when it came through the viewfinder.
Flight Radar 24 did identify this one. It is an American Eagle flight from Charlotte, N.C. to Jackson, MS, on a Canadair CRJ-700 with an altitude of 34,000 feet:
PS - There are several shots of various planes crossing the Moon on my smugmug page (linked in my signature), in the "Planes" gallery.

Your one of those Lunartics!
Great shots.
