Next, you'll need some extra in-flight entertainment to help pass the time. A juicy book and a laptop filled with your favourite movies are some fantastic options. If you intend to catch forty winks, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, leave space for a toothbrush and some facial wipes so you'll arrive at your destination looking fresh and raring to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items differs between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, blades, aerosol cans and flares. Sporting equipment like ski poles, and objects that could harm other people, such as pepper spray and firearms, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - The aisles of an airplane aren't the place for a fashion parade. Layer your clothing and choose shoes that are roomy, flat and easy to remove. > - Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Greenbelt? > - Your ID and travel documents will need to be inspected by airport security personnel. Keep them at hand so you don't hold up the queue. > - The X-ray machine comes next. Remove anything on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt. > - All your electronics, including your phone and laptop, are also required to be scanned. > - Remember to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag. > - The right choice of footwear can save you several minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on sneakers usually aren't. > - Airlines will not allow any pocket knives or other sharp items in the cabin. If you need to bring these kinds of items, pack them safely in your checked luggage. __Flights to Greenbelt information__ | Destination airport | Washington Dulles Intl. | | ----------------------------- | ----------------------- | | Destination airport IATA code | IAD | | Destination city name | Washington | | Return price | £316 | ## Trending flights to Greenbelt Prices were available within the past 7 days and start at £325 for one-way flights and £316 for round trip, for the period specified.
