We've rounded up all the info you need to make your flight a stress-free experience. Follow our insider tips and you'll be speeding through the airport and having a blast in Porto in no time. What to pack in your hand luggage:

• The trick to having an amazing flight experience is to pack in advance. Start with the essentials: passport, travel docs, credit cards and important medications. Next, bring items that'll help pass the time, like some electronic devices or a juicy novel. It's also smart to pack your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to pop in toiletries like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a sharp object hiding in one of the compartments of your hand luggage. Other restricted items include explosive or flammable products, such as fuel and matches, 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 main priority when choosing what to wear during your flight. Loose, breathable clothing is a smart option, as are flat, closed-toe shoes.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To lessen your risk on board, drink plenty of water, consider wearing compression socks and keep your legs and feet moving.

Being organised before your flight will make your trip to Porto a piece of cake. Check out our useful tips for a swift journey through security:

• Security personnel first need to verify that you have a valid passport and matching travel documents before you can proceed any further. Have them ready for inspection.
• Your jacket, belt, keys and other items in your pocket, like your earphones, will be required to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
• All your electronic devices, including your tablet and phone, must also be separately scanned.
• Any gels or liquids, such as shampoo or hand cream, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
• Slip-on shoes are a sensible footwear choice as you're less likely to be required to remove them when going through security. Big boots and other bulky shoes are usually subjected to extra screening.
• Pocket knives and other sharp items are not allowed in the cabin. They'll be confiscated at security, so put them in your checked luggage.
