In the old days before TSA I always brought a spray bottle of toner and periodically sprayed my face during flights of any duration. I wear foundation makeup when I get on the plane,but not powder and use face cleansing towlettes extensively both before sleeping on overnight flights and also upon awakening. I always bring cream moisturizer for overnights and apply blush and eye shadow, and mascara (I am blonde so I need the boost!) when I wake up. I don't use any foundation or BB cream when I wake up, because I like to take a shower first. Drink lots of water and avoid salt.

Oh and I forgot, take off your lenses and wear glasses during the flight, then put the lenses in when you get refreshed in the AM.
