Don't cry for me (I'll do that myself), rather, let's look for the positive in the situation. For example, I was once was an uninformed over-packer turned savvy traveler. Let me show you a few lifesavers that have made extensive travel a bit more tolerable.
My boyfriend bought this for me when he thought my ratty, old Longchamp had seen better days and too many airplane floors. Best travel tote, ever. It holds my 20 lb computer along with (but not limited to) an overstuffed wallet, bottled water, several magazines, sunglasses, two blackberries, and my sanity.
You need a lightweight scarf on a plane. Whether you use as a pillow, blanket, or to hide your face from plane talkers (ugh), this is your lifeline. (Oh, hi Alli)
Every time I see someone wearing heels at the airport, I wince out of pain for them. The last thing you want to be doing is schlepping your bulging carry-on down a moving walkway only to have your heel get stuck in the metal grid. Yes, it's happened to me.
Do you have any travel secrets?
