Pashminas are a staple when traveling. You can easily use them for a blanket, too (and they don't have to be the real thing. I have tons in my closet from good 'ol Chinatown.) Also, in the summertime, I like to wear my flats without socks. I can't tell you how many nightmares I had the first time I had to take them off and walk barefoot through the metal detector. NEVER AGAIN! I wear those little half socks only for that portion, and then tuck them in my bag. I advise you do the same...
I've been to some great airports and then I've been to some horrible ones. I've never been to one that the interior was amazing, so I decided to do a little research and now I totally know what airports to fly in:
Airport in Wellington, Arizona
Hope I've psyched you up for some traveling!
