Do you have any tips for my flight to Portsmouth?
We've pulled together all the info you need to make your flight a stress-free experience. Follow our tips and you'll be hightailing it through airport security and having a blast in Portsmouth in no time. What to pack in your hand luggage:
  • First and foremost, pack your passport, travel documents, cash and daily medications. Next, you'll want some entertainment to help pass the time. A thrilling novel and a tablet filled with your favourite shows are some fantastic options. If you plan to take a quick snooze, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a few toiletry items so you'll arrive looking fresh and raring to go.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items can differ between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes tools, metal cutlery, aerosol cans and bleaching agents. Sports equipment like ice skates, and objects that could injure passengers, such as swords and batons, won't be allowed on board either.
What to wear on a flight:
  • You'll want to go for comfort over style. Prepare for temperature changes in the cabin by donning layers, and opt for closed-toe, flat footwear like slip-ons.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clotting due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.
How to get through airport security fast when flying to Portsmouth?
Being organised before your flight will help make your getaway to Portsmouth quick and painless. Read through our top tips for a stress-free journey through security:
  • First things first. Your passport and boarding pass will need to be shown to security personnel. Keep them handy so you don't have to dig around for them.
  • Time to strip down. Well sort of. Your belt, coat, keys and other small items, like your earphones, will be required to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
  • For just a few minutes, you'll have to unplug from technology. Your tablet, phone and any other electronic gadgets will also need to go through the scanner.
  • Remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when going through security. Big boots and other heavy-style shoes are often subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked suitcase. They won't be allowed on board.
