Do you have any tips for my flight to Cornwall?
If you're not prepared, airports and flying can be a real challenge. But there's no need to panic. Follow these handy hints and enjoy a pain-free start to your getaway in Cornwall. What to pack in your hand luggage:

  • First things first, pack in your passport, important documents, credit cards and medications. Next, you'll need some extra in-flight entertainment to while away the hours. A juicy book and a laptop crammed with your favourite shows are always good options. If you intend to catch up on some sleep, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, find room for a toothbrush and some facial wipes to ensure you arrive at your destination feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes knives, scissors, spray paint and flares. Sporting equipment like golf clubs, and items that could harm other people, such as swords and batons, are also banned from the cabin.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Wear layers and opt for shoes that are flat, enclosed and easy to take on and off.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to improve your circulation.

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

  • Airport security personnel first need to know that you have a valid passport and travel documents before you're allowed to proceed any further. Have them close by, ready for inspection.
  • Your belt, jacket, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them as your turn draws near.
  • Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online in no time.
  • Want to bring along your favourite cologne? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you're permitted to bring it with you in your carry-on baggage.
  • Slip-on shoes are a great footwear choice as you're less likely to be required to remove them when going through security. Boots and heavier-style shoes are usually subjected to extra screening.
  • Take all prohibited items out of 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 in the cabin.
