I hate red eyes, but I also hate wasting a day traveling home from the west coast so here is what I do:
- I carry the Oil of Olay face wipes. I wet it down and give myself a quick wipe-down of my face, arms, under arms, neck
- I brush my teeth. Even though the flight is around the same length whether it is during the day or night, when I sleep the dry air = horrible breath. Gum helps, but nothing is as nice as brushing my teeth
- Apply fresh deodorant
- I always carry my own blanket and pillow when I have a scheduled red eye. Most airlines do not provide them in economy anymore so you either need to buy one in the airport or from the flight crew.
- Eye shades and ear plugs are a must!
Also, be careful when you put stuff in the seat back pocket if you plan on falling asleep.
