Firstly, you'll need basic toiletry items, such as deodorant, toothpaste and a toothbrush, a fresh change of clothes and a good novel. Secondly, leave space in your carry-on bag for your laptop, a charger, your medications and perhaps a blow-up neck pillow as well. Lastly, don't forget to take your passport, travel documents and your credit cards. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have a Swiss Army knife hiding in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable goods, such as bleach and fuel, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Comfort should be your top priority when deciding what to wear during your flight. Loose clothing is a wise choice, as are flat, closed-toe shoes. > - Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs and feet moving and wearing compression socks to help improve your circulation. ### How to get through airport security fast when flying to Chelmsford? > - Be sure to keep your travel documents and ID handy. They're the first items you'll be asked to present to security. > - Time to strip down. Well kind of. Your belt, jacket, keys and other items in your pocket, like coins, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives. > - Your electronic gadgets like phones and laptops will also have to go through the machine for inspection. Don't worry, you'll be back online before you know it. > - Travelling with your favourite perfume? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can bring it with you in your carry-on baggage. > - Slip-on shoes are a clever footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other heavy shoes are usually subjected to extra screening. > - Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won't be allowed on board. __Flights to Chelmsford information__ | Destination airport | Greater Sudbury | | ----------------------------- | --------------- | | Destination airport IATA code | YSB | | Destination city name | Sudbury | | Return price | £215 | ## Trending flights to Chelmsford Prices were available within the past 7 days and start at £109 for one-way flights and £215 for round trip, for the period specified.
