Firstly, you'll want some basic toiletries, such as a toothbrush and lip balm, a fresh set of clothes and a good book. Secondly, make room in your bag for your electronic gadgets, chargers, your important medications and perhaps a cosy neck pillow as well. Last, but definitely not least, don't forget to bring your passport, travel papers and some money. > > > Do not pack the following items in your hand luggage: > > > - Make sure you don't have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other restricted items include flammable or explosive goods, 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: > > > - The aisles of an airplane are no place for a fashion parade. Wear layers and choose shoes that are flat, enclosed and easy to take on and off. > - Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To minimize your risk on board, drink plenty of water, consider wearing compression socks and keep your legs and feet moving. ### How to get through airport security fast when flying to Dem? > - First things first. Your boarding pass and travel ID will need to be shown to airport security. Keep them someplace accessible to avoid fumbling around for them. > - Time to strip down. Well kind of. Your jacket, belt, keys and other items in your pocket, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them before your turn. > - All your electronic gadgets, including your phone and laptop, will also need to be separately scanned. > - Travelling with a new hand cream? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you on board. > - There's a chance you'll be asked to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a good idea. > - Sharp items are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked baggage. __Flights to Dem information__ | Destination airport | Dr. Francisco de Sa Carneiro | | ----------------------------- | ---------------------------- | | Destination airport IATA code | OPO | | Destination city name | Porto | | Return price | £39 | ## Trending flights to Dem Prices were available within the past 7 days and start at £20 for one-way flights and £39 for round trip, for the period specified.
