Start with the essentials: passport, travel docs, bank cards and important medications. Next, bring on board items that'll help keep you entertained, like some electronic devices or a good book. You'll also want to bring your chargers, a quality neck pillow and a pair of headphones. And of course, be sure to toss in toiletries like a toothbrush, deodorant and a spare change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Put all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, chemicals agents and gasoline, are also restricted. > > > What to wear on a flight: > > > - The key to a comfortable flight is as simple as the clothes you wear. Prepare yourself for varying temperatures by bringing layers. This will keep you nice and warm if the cabin begins to cool down. Shoes like high heels and sandals are best left for other occasions. Even though they may be your favourites, opt for flat, closed-toed footwear like sneakers. Your feet will appreciate it. > - Most of us have heard about DVT (deep vein thrombosis), a blood clotting condition caused by prolonged periods of sitting. There are plenty of ways to lower your risk. Wear compression tights or socks, stay hydrated and keep your legs and feet moving. Do a lap or two of the cabin or perform some stretches in your seat. ### How to get through airport security fast when flying to Grendon Underwood? > - Airport security personnel first need to establish that you have a valid ID and boarding pass before anything else. Keep them close by. > - The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening. > - All your electronics, including your phone and laptop, must also be scanned. > - Travelling with a new perfume or cologne? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you're permitted to bring it with you in your carry-on bag. > - The right choice of footwear can save you several minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Slip-on shoes usually aren't. > - Sharp or pointed objects (like knives and scissors) are not allowed on board. They'll be seized at security, so put them in your checked luggage. ## Book with confidence # Expedia flights to Grendon Underwood Searching for cheap flights to Grendon Underwood?
