There are multiple problems here, even in the later images. I'll stick to the glare problem. If you are shooting through glass, in addition to the good tips already given, you should ensure that you are wearing dark clothes. If you have light-colored hair, or like myself, a distinct lack of it, you should wear a dark hat too.
Next time you shoot through glass, if you see indistinct glare, move your body around. If the glare changes or moves, then you are the source of the glare-wear darker clothes. Also, when in the terminal, don't position yourself with a bright wall to your rear, and avoid the lights from restaurants and newsstands.
Now, I know Colin is very well experienced, but even if he sent one to me for free, you won't see me with a dark hood around my head and camera at ANY airport these days. Though technically, it sounds like the best idea of all.
That 150702_4 takeoff shot-maybe if it was taken on a better day, with less smog and haze.
