First of all you'll need toiletry items, such as lip balm and hand cream, a spare set of clothes and a good novel. Next, find a spot in your carry-on bag for your electronic gadgets, chargers, your important medications and perhaps a proper neck pillow too. Lastly, and most importantly, don't forget to bring your passport, travel docs and some cash. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items differs between airlines, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes things like knives, scissors, spray paint and fireworks. Sports equipment like ice skates, and items that could injure passengers, such as firearms and swords, can't come on board with you either. > > > What to wear on a flight: > > > - Comfort should be your top priority when deciding what to wear during your flight. Loose, breathable clothing is a sensible choice, as are flat, slightly roomy shoes. > - The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Lower your risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks to help your circulation. ### How to get through airport security fast when flying to Dulles? > - Security personnel first need to check that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them within easy reach, ready for inspection. > - Next up, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Items like your jacket, belt and earphones will be required to go through the machine. > - For just a few minutes, you'll have to unplug from the digital world. Your phone, laptop and any other electronics will need to go through the scanner. > - Want to bring along your favourite hand and nail cream? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, it's OK to bring with you on board. > - Lightweight sneakers are a clever footwear choice as you're less likely to have to remove them when passing through security. Hiking boots and other heavy shoes are often subjected to additional screening. > - Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed in the cabin. ## Book with confidence # Expedia flights to Dulles Searching for cheap flights to Dulles?
