Do you have any tips for my flight to Cross Keys?
We've got the lowdown on how to make your journey as pain-free as possible. Follow our insider tips and you'll be zooming through airport security and enjoying Cross Keys in next to no time. What to pack in your hand luggage:

  • A plane trip can be a comfortable experience if you carry the right gear. First things first, you'll need basic toiletries, such as deodorant and a toothbrush, a clean pair of socks and a good book. Next, find a spot in your bag for your electronic gadgets, chargers, any daily medications and perhaps a quality neck pillow too. Lastly, and most importantly, remember to take your passport, travel documents and some money.

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 avoid carrying anything flammable, sharp or explosive. This includes box cutters, razor blades, fuel and fireworks. Sports equipment like hockey sticks, and items that could injure passengers, such as firearms and ammunition, are also banned from the cabin.

What to wear on a flight:

  • Your main aim is to feel as comfortable as you can. Go for easy-to-remove footwear, dress in loose, natural-fibre clothing and remember to bring a sweater in case you get cold in the cabin.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lower your risk on board, drink plenty of water, consider wearing compression tights or socks and move your legs and feet often.

How to get through airport security fast when flying to Cross Keys?
It's all about being organised. We've put together some top tips for a speedy trip through security. Look out Cross Keys, here you come:

  • Be sure to have your ID and boarding pass within easy reach. They're the first items you'll be asked to show at airport security.
  • After that, both you and your hand luggage must be X-rayed. To speed things up, remove anything that might trigger the alarms. Personal belongings like your coat, belt and earphones need to go through the machine.
  • All your electronics, including your phone and tablet, must also be separately scanned.
  • Want to bring along your favourite perfume or cologne? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's fine to bring with you in your carry-on bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when passing through security. Big boots and other bulky shoes are usually subjected to additional screening.
  • Knives and other sharp items can't be taken on board. They'll be confiscated at security, so pack them safely away in your checked suitcase.
