Do you have any tips for my flight to Portsmouth?
We've rounded up all the info you need to make your flight a pleasant experience. Follow our tips and tricks and you'll be breezing through airport security and having a blast in Portsmouth in no time flat. What to pack in your hand luggage:

  • It's easy — first, put in your passport, travel documents, credit cards and daily medications. Next, you'll need some entertainment to while away the time. A thrilling novel and a laptop filled with your favourite movies are some terrific options. If you hope to take a short nap, a neck pillow and some earplugs will also come in handy. Finally, leave some space for a toothbrush and some deodorant to ensure you arrive at your destination feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like your Swiss Army knife, and dangerous goods which are flammable or explosive, such as aerosols and gasoline, are also not allowed.

What to wear on a flight:

  • Your aim is to feel as comfortable as possible. Opt for a pair of flat, closed-toe shoes, dress in loose, natural-fibre clothing and remember to take a pullover in case you get cold in the cabin.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Lower your risks by drinking water, keeping your legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Portsmouth?
It's simple — be prepared. We've rounded up some useful tips for an easy trip through airport security. Watch out Portsmouth, here you come:

  • Be sure to have your passport and boarding pass someplace easily accessible. They're the first items you'll be asked for by airport security.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Items such as your belt, jacket and earphones will be required to go through the machine.
  • For just a few moments, you'll have to unplug from the digital world. Your laptop, phone and any other electronics must also go through the scanner.
  • Want to bring along your favourite perfume? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can keep it with you on board.
  • Choosing your footwear wisely can save you a few precious minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed on board.
