Do you have any tips for my flight to Three Mile Bay?
Depending on where you're coming from, your journey to Three Mile Bay could be a piece of cake or it could go on forever. Below are some handy tips that will help you start your next great adventure on the right foot. What to pack in your hand luggage:
  • First of all, put in your passport, travel docs, bank cards and medications. Next, you'll want some entertainment to while away the hours. A juicy book and a tablet filled with your favourite shows are some terrific options. If you hope to take a short snooze, a quality neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some cleansing wipes so you'll arrive at your destination feeling fresh and ready to go.
Do not pack the following items in your hand luggage:
  • While the list of restricted items can differ between airlines, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, pocket knives, fuels and bleaching agents. Sports equipment like ice skates, and items that could injure passengers, such as pepper spray and guns, are also banned from the cabin.
What to wear on a flight:
  • The aisles of an airplane are no place for a fashion parade. Dress in comfortable layers and choose shoes that are enclosed, flat and easy to pull on and off.
  • You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression socks and keep your legs and feet moving.
How to get through airport security fast when flying to Three Mile Bay?
The answer is — be prepared. We've pulled together some top tips for a speedy trip through airport security. Watch out Three Mile Bay, here you come:
  • Airport security personnel first need to check that you have a valid passport and boarding pass before anything else. Have them within easy reach, ready for inspection.
  • 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 things like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All your electronic devices, including your tablet and phone, must also be scanned.
  • Can't travel without your favourite cologne or perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're permitted to bring it with you in your carry-on.
  • Lightweight sneakers are a clever footwear choice as you're less likely to have to remove them when going through security. Big boots and heavier-style shoes are often subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won't be allowed in the cabin.
