Next, you'll want some extra in-flight entertainment to help pass the time. A juicy book and a tablet crammed with your favourite movies are some wonderful options. If you hope to catch forty winks, a comfy neck pillow and some earplugs will also be useful. Finally, squeeze in a toothbrush and some deodorant to ensure you hop off the plane looking and feeling fresh. > > > Do not pack the following items in your hand luggage: > > > - Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your beloved pocket knife, and products which are explosive or flammable, such as flares, bleaching agents and matches, are also prohibited. > > > What to wear on a flight: > > > - Your goal here is to be as comfortable as you can. Choose shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and remember to take a sweater in case it gets cold in the cabin. > - Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-distance flights. Lower your risks by drinking water, keeping your legs and feet moving and wearing compression socks or tights. ### How to get through airport security fast when flying to San Francisco? > - Airport security personnel first need to see that you have a valid ID and matching travel documents before you can proceed any further. Have them within easy reach, ready for inspection. > - Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt. > - Electronic devices like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online before you know it. > - Any gels or liquids, such as perfume or hairspray, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres).
