Start with the essentials: passport, official ID, cash and important medications. Next, take on board items that'll help while away those hours, like some electronic devices or a good book. It's also smart to pack your chargers, a comfy neck pillow and a pair of earplugs. And of course, be sure to toss in toiletry items like a toothbrush, deodorant and a spare change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Pack all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Sharp objects, like your beloved Swiss Army knife, and products which are explosive or flammable, such as flares, chemicals agents and matches, are also prohibited. > > > What to wear on a flight: > > > - The answer to a comfortable flight often lies in your clothing choices. Prepare yourself for varying temperatures by bringing layers. That way you'll stay nice and warm if the cabin begins to cool down. Shoes like sandals and heels are best left for other occasions. Instead, opt for flat, closed-toed footwear like sneakers. Your feet will thank you for it. > - Caused by sustained periods of immobility, DVT (deep vein thrombosis) is a blood clotting condition that can affect passengers on long-haul flights. But the good news is there are ways to reduce your risk of developing it. Drink plenty of water, walk around the cabin whenever possible and wear compression tights or socks. ### How to get through airport security fast when flying to Forest Knolls? > - Airport security personnel first need to establish that you have a valid passport and matching boarding pass before you can proceed any further. Have them ready to show. > - After that, both you and your hand luggage must be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings like your belt, coat and earphones need to go through the machine. > - All your electronic devices, including your tablet and phone, will also need to be separately scanned. > - Don't forget to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one litre), clear zip-lock bag. > - It's also likely that you'll be required to take your shoes off to be X-rayed, so wearing slip-on shoes is always a smart idea. > - Airlines will not allow any sharp items or pocket knives in the cabin. If you must bring these kinds of items, pack them in your checked baggage. ## Book with confidence # Expedia flights to Forest Knolls Searching for cheap flights to Forest Knolls?
