A magazine- for when your brain just refuses to concentrate on the work you've brought with you.
A wrap/scarf- I've found that no airport or plane is ever consistent with its temperature control, so a wrap is a great way to stay warm when the ac is super strong, and it can double as a blanket when you find yourself asleep huddled into a ball while waiting for your flight.
Hand sanitizer- always necessary!
Sunglasses- especially if you're super tired for an early morning flight, these are great for take-off and landing
A healthy snack- If you're crossing borders, fruits and veggies are a no-no, so try to pack something that at least tastes like real fruit. I find various nuts are also good, if unsalted (remember no liquids, and beverages in airports can be expensive, so no need to make yourself extra thirsty!).
Gum- My ears can be sensitive to the change in pressure, so I chew gum to help my ears 'pop'. And I love the extra kick of energy I get from these!
Ipod with good headphones- I load mine up with several days worth of news podcasts to stay entertained (and informed!) I also create various playlists- one for napping, one for waking up from my nap, one for reading, and one to seat-dance to.
Flip flops- easiest to get on an off in security lines. Plus their super comfortable. Although I wouldn't recommend them if you have limited time between flights and have to run in the airport. I'm a klutz and tend to trip when I run in my flip flops, so if I have to run, I wear comfy ballet flats.
Big headband or a hat- My hair always gets kinda frizzy when I fly, so I always bring a big headband or a hat to cover my bad hair. And this one from Vineyard Vines is amazingly cute!
Notebooks- You never know when inspiration is going to strike! I love Moleskin notebooks. I alway have one on me to jot down random thought. I'm also always making lists and plans, which tend to get lost in my mind unless I write them down.
Pens- For writing in notebooks and for filling out necessary travel documents like customs declaration forms and travel tags.
Lysol to go- For those of us who are a germaphobes.
Throat Lozenges- My throat tends to get dry very easily on planes, so I always keep a couple of these on hand.
Emergen-C- This stuff i great! It gives me a boost of energy and vitamins, and it's great for travel. If I have room I normally bring a small Nalgene with me so I can fill it with water after security and add one of these packets. They're also pretty yummy.
Zip top tote- I love Lands' End's zip top tote. I always bring my large black and pink one when I travel because it fits so much, has plenty of pockets for easy organization, and has the added security of a zip top. I'm always worried someone can reach into my purse and steal my passport, ipod, wallet, etc, so this bag gives me a little peace of mind.
For those of you traveling this summer, may your flights be on time, the people sitting around you be kind, and your destinations be fabulous!
