Well I know you maybe thinking I can't afford that, well even an old cashmere sweater can double as a throw. They are perfect for going between you and the awful blankets and pillows the airlines give you. It's the only way I can get my son to even touch one of those scratchy pillows.
Mine was a gift from GQ (Smythson of Bond Street) and I first thought what would I need that for but actually it's literally the first thing I pack and the most important travel essential. I keep my passport, my airline tickets, baggage receipts, Airline Frequent Flier cards, foreign currency, a pen and just about any thing I might need to access quickly!
Well obviously a compact camera! My personal favorite is the Sony RX-1 but the Sony RX-100 is a great camera too. Have the camera handy during the flight as there are often fabulous shots to be taken directly out the window.
I like the soft oiled canvas bags and my favorite one comes from Jack Spade. Mine is big enough for my 17" laptop and as a result big enough for a lot more too. Get one with a shoulder strap but also with handles so you don't need to ruin your jacket if you've stuffed your carry on for a weekend getaway.
Look even when you are lucky enough to fly in business or 1st most of the time they don't have your favorite snack or if they do you should be eating something a little less calorific... I love roasted unsalted almonds from whole foods and trail mix bars - I am part squirrel if you wondered.
Flying from New York to Paris might sound glamorous but only if you do it in style! I spend many months of the year away from home traveling to both exotic and mundane locations, so regardless of the class I am flying in, there are a few things I always take for the trip that help me travel with style.
