How to survive the flight to Radcliff?
We’ve rounded up all the info you need to make your journey an enjoyable experience. Follow our insider tips and you’ll be speeding through airport security and seeing the best of Radcliff in no time flat.What to pack in your hand luggage:

  • A plane ride can be a stress-free experience if you carry the right gear. Firstly, you’ll want some basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a fresh change of clothes and a good read. Secondly, leave space in your hand luggage for your mobile phone, a charger, your medications and perhaps a proper neck pillow too. Last, but definitely not least, be sure to bring your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) won’t be allowed on. Sharp or pointed objects, like your beloved Swiss Army knife, and dangerous products which are explosive or flammable, such as flares, chemicals agents and matches, are also not allowed.

What to wear on a flight:

  • The best way to ensure a comfortable flight is often as simple as your choice of clothes. Prepare for temperature changes by layering up. This will keep you nice and warm if the cabin gets chilly. Shoes like stilettos, flip flops and lace-up boots are best left for other occasions. Even though they may be your favorites, go for flat, closed-toed footwear like sneakers. Your feet will thank you later.
  • A condition by the name of DVT (deep vein thrombosis) is a potential risk on long-haul flights. It results from blood clotting due to poor circulation. Doing regular leg and foot exercises while seated is a great way to prevent this occurring. Wearing a good-quality pair of compression socks is also a wise idea.

How to get through airport security fast when flying to Radcliff?
A little pre-planning before you arrive at the airport will help make your getaway to Radcliff a breeze. Check out our handy tips and tricks for a stress-free journey past security:

  • Keep your ID and travel documents close by. They’ll be the first things you’ll be asked to present to airport security.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the scanner’s alarm. This includes items like headphones or earphones, as well as heavy jackets or coats. They’ll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your laptop and phone, will also need to be scanned.
  • Remember to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one liter), clear zip-lock bag.
  • It’s also likely that you’ll be required to remove your shoes for scanning, so wearing slip-on shoes is always a clever idea.
  • Sharp or pointed objects (like knives and scissors) are prohibited in the cabin. They’ll be seized at security, so put them in your checked baggage.
