How to survive the flight to Keyes?
If you're poorly prepared, airports and flying can be tough. But there's no need to panic. Follow these helpful hints and enjoy a trouble-free start to your time in Keyes.What to pack in your hand luggage:
  • Traveling on a plane can be a great experience if you take the right gear. Firstly, you'll need basic toiletries, such as deodorant and a toothbrush, a spare pair of socks and a good novel. Secondly, find room in your carry-on bag for your mobile phone, a charger, your medications and perhaps a comfy neck pillow as well. Lastly, and most importantly, don't forget to take your passport, travel papers and some money.
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 avoid carrying anything sharp, flammable or explosive. This includes knives, scissors, fireworks and fuel. Sporting equipment like ice skates, and objects that could injure passengers, such as swords and guns, aren't allowed in the cabin either.
What to wear on a flight:
  • The answer to a comfortable flight can be as simple as your choice in clothes. Prepare for temperature changes by layering up. That way you'll stay nice and warm if the cabin gets chilly. Shoes like high heels and sandals are best left in your suitcase. Instead, go for flat, closed-toed footwear like sneakers. Your feet will thank you for it.
  • Caused by sustained periods of immobility, DVT (deep vein thrombosis) is a blood clot condition that can affect some passengers during long-haul flights. The great news is there are numerous ways to significantly reduce your risk of developing it. Keep your fluids up, wander around the cabin wherever possible and wear compression tights or socks.
How to get through airport security fast when flying to Keyes?
The answer is simple — be organized. We've put together some top tips for a stress-free trip through security. Watch out Keyes, here you come:
  • Your passport and boarding pass will need to be inspected by airport security personnel. Keep them within easy reach to avoid fumbling around for them.
  • Time to strip down. Well sort of. Your belt, coat, keys and other small items, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • All electronic devices, including your phone and tablet, are also required to be separately scanned.
  • Remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag.
  • Slip-on shoes are a great footwear choice as you're less likely to have to remove them when passing through security. Safety boots and other bulky shoes are usually subjected to extra 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 luggage.
