Do you have any tips for my flight to Flat River?
Depending on where you're coming from, your trip to Flat River could be as easy as pie or it could go on forever. We've put together some useful tips that will help you start your next big adventure on the right foot. What to pack in your hand luggage:
  • A plane ride can be a pleasure if you pack the right stuff. First things first, you'll need basic toiletry items, such as a toothbrush and some deodorant, a fresh change of clothes and a few magazines. Secondly, find a spot in your bag for your electronic gadgets, chargers, your medications and perhaps a neck pillow as well. Lastly, don't forget to take your passport, travel papers and some money.
Do not pack the following items in your hand luggage:
  • Make sure you don't have a Swiss Army knife hiding in one of the zippers of your carry-on luggage. Other prohibited items include flammable or explosive goods, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Comfort should be your main concern when choosing what to wear on board. Loose clothing is a wise option, as are flat, slightly roomy shoes.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To minimize your risk on board, drink lots of water, consider wearing compression tights or socks and keep your feet and legs moving.
How to get through airport security fast when flying to Flat River?
A little pre-planning before you arrive at the airport will help make your getaway to Flat River a piece of cake. Below are some handy tips and tricks for a stress-free journey past security:
  • Your boarding pass and passport will need to be presented to airport security. Have them close by so you don't hold up the line.
  • Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Items such as your coat, belt and headphones need to go through the machine.
  • For just a few minutes, you'll have to unplug from technology. Your phone, laptop and any other electronic gadgets will also need to go through the scanner.
  • Travelling with a new hand cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you're permitted to bring it with you on board.
  • Choosing your footwear wisely can save you valuable minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Knives and other sharp items can't be taken on board. They'll be confiscated at security, so put them in your checked baggage.
