Indoors Outdoors

If you are indoors standing below a skylight letting in the outdoors, does the painting you do qualify as a plein air work?

I was in LAX (Los Angeles International Airport) waiting to catch a flight. I was standing in a long line, so I did this small 6" x 9" painting.

If you have the proper kit, you can do a painting while standing, sitting, squatting or lying down. I haven't yet tried to do one while walking. If you do one, I'd like to see it.
