Do you have any tips for my flight to Portsmith?
Depending on where you're coming from, your journey to Portsmith could be no sweat at all or it could drag on forever. We've put together some useful hints that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • A plane trip can be a pleasure if you carry the right stuff. First of all you'll need basic toiletries, such as deodorant and a toothbrush, a fresh change of clothes and a magazine or two. Next, find room in your hand luggage for your mobile phone, a charger, your important medications and maybe a blow-up neck pillow too. Last, but definitely not least, remember to take your passport, travel docs and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, blades, fuel and fireworks. Sporting equipment like baseball bats, and items that could harm passengers, such as swords and batons, are also banned from the cabin.

What to wear on a flight:

  • Your top priority is to feel as comfortable as you can. Pick a pair of slip-on shoes, dress in loose, natural-fibre clothing and remember to take a sweater in case it gets chilly in the cabin.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long-haul flights. Lower your risks by staying hydrated, keeping your feet and legs moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Portsmith?
As savvy travellers know, the secret is to be well prepared before you get to the security gate. That way, you'll be hopping onto that plane to Portsmith in no time at all. Follow these helpful tips and get your holiday off to a fantastic start:

  • Your boarding pass and travel ID will need to be inspected by security personnel. Have them close by so you don't hold up the queue.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Personal belongings like your belt, coat and headphones need to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go on a tray for inspection. No need to worry though, you'll be back online before you know it.
  • Can't travel without your favourite perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're allowed to bring it with you in your carry-on bag.
  • There's a chance you'll be required to take your shoes off for scanning, so wearing slip-on sneakers is always a smart idea.
  • Sharp items like knives are not allowed on board. They'll be seized at security, so pack them in your checked suitcase.
