Hey Wanna fly, Keep your make-up not too heavy, but enough to notice that you have some on. I used earthy tones on my eyes, (so yes, deffinately wear some eye-shadow) and they love to see a red or brown lipstick on your pucker (since this is a uniform requirment)
Keep your grooming extreemly neat (hair completely back with no fly-away bits or falling on your face) and make sure your nails are well manicured (either clear, french or very light pink polish) but most of all, remember to keep a big smile on your face at all times
Best of luck!
Cheers
