My travel buddy on our 10 hour flight to London from SFO. When he put on his dust mask, he asked, "Are you going to be embarrassed?"Greetings from London! It's Day One, and I've literally been on planes, trains, and automobiles...all in a span of 24 hours, with little sleep, and no clue what time it is anywhere. In fact, I'm writing this on adrenaline alone, so please forgive any grammatical or spelling mistakes...But putting aside travel weariness, here's the question I'd like to propose to all of you dear readers: How do you handle long trips and jet lag? Thus far, I've concocted my own essentials to dealing with long plane rides in particular: With space at a minimum, it's hard to get comfortable (unless you are prepared to drop some coin on a first class ticket with those fold out seat-beds!), so here is my list of must-haves that I bring along in my carry-on: 1. A headrest pillow. I always kick myself when I forget it because when I start dozing off, I do the head-bob jerk which is the worst. Or I find myself in an awkward situation if I happen to be sitting next to a complete stranger and wake up leaning on their shoulder. 2. A sweater or a blanket. No matter if it's the dead of summer, airplanes tend to get chilly; so it's always a good idea to bring an extra layer of protection. 3. Water. With security measures being what they are, I tote around an empty Nalgene bottle and fill it up at a water fountain. 4. Xanax. (Just kidding. But not really.) 5. Entertainment. Although this one is becoming obsolete. So many planes now offer a vast amount of in-flight movies, TV shows, and music; i.e. my flight had about 60 movies available to watch on demand.
