First of all you'll need basic toiletry items, such as a toothbrush and lip balm, a spare set of clothes and a good read. Secondly, make room in your hand luggage for your electronic devices, chargers, medications and maybe a proper neck pillow as well. Lastly, and most importantly, don't forget to bring your passport, travel docs and your credit cards. > > > Do not pack the following items in your hand luggage: > > > - Double-check that you don't have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other restricted items include explosive or flammable substances, such as fuel and fireworks, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Your priority is to be as comfortable as possible. Pick flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to take a sweater in case you get cold in the cabin. > - Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Reduce the risks by staying hydrated, keeping your ankles and legs moving and wearing compression socks to help improve your circulation. ### How to get through airport security fast when flying to Siuntio? > - Be sure to keep your boarding pass and passport within easy reach. They're the first items you'll be asked to show at security. > - The X-ray machine is up next. Empty your pockets and remove anything that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt. > - All electronic devices, including your phone and laptop, will also need to be scanned separately. > - Remove all gels and liquids from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag. > - It's also possible you'll be required to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a good idea. > - Knives and other sharp items are prohibited in the cabin. They'll be confiscated at security, so put them in your checked luggage. __Flights to Siuntio information__ | Destination airport | Vantaa | | ----------------------------- | -------- | | Destination airport IATA code | HEL | | Destination city name | Helsinki | | Return price | £45 | ## Trending flights to Siuntio Prices were available within the past 7 days and start at £21 for one-way flights and £45 for round trip, for the period specified.
