The first seems a little low on contrast, but is otherwise Ok.
The runway shot could use a tad more sharpening and I would add a dash of contrast and vibrance. Really unique shot!
The last one is definitely a bit noisy, and I personally would crop it a little bit tighter. The lighting isnt ideal, so it seems a little flat as well.
