It's also smart to bring your chargers, a quality neck pillow and a pair of earplugs. Last but not least, don't forget to pop in toiletries like a toothbrush, cleansing wipes and a spare set of clothes. > > > Do not pack the following items in your hand luggage: > > > - Squeeze all your full-sized bottles of shampoo and conditioner in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp or pointed objects, like your Swiss Army knife, and dangerous goods which are flammable or explosive, such as spray paint, flares and poisons, are also banned. > > > What to wear on a flight: > > > - Your aim here is to be as comfortable as you can. Go for shoes that are easy to pull on and off, dress in loose, natural fibers and remember to bring a sweater in case you get cold in the cabin. > - Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clots forming due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks. ### How to get through airport security fast when flying to Firth? > - Airport security personnel first need to check that you have a valid passport and travel documents before you can proceed any further. Have them ready for inspection. > - Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt. > - Your electronic gadgets 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 shampoo or hand cream, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag. > - The right choice of footwear can save you a few precious minutes. Boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not. > - Sharp or pointed items are not allowed in the cabin.
