How to survive the flight to Flat River?
If you're not prepared, travelling can be testing. But there's no need to worry. Follow these handy tips for a stress-free start to your holiday in Flat River.What to pack in your hand luggage:

  • The secret to having a stress-free flight experience is to be prepared. So, let's start with the basics: passport, official ID, cash and daily medications. Next, take on board items that'll help pass the time, like your laptop or a good book. It's also wise to bring your chargers, a neck pillow and a pair of earplugs. Last but not least, don't forget to toss in toiletry items like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp or pointed objects, like your beloved Swiss Army knife, and products which are flammable or explosive, such as flares, chemicals agents and matches, are also restricted.

What to wear on a flight:

  • The aisles of your aircraft are not the best place for a fashion parade. Wear comfortable clothes and pack a sweater as it can get quite cool in the cabin during long-haul flights. Enclosed, flat shoes are always a good choice too.
  • Unfortunately, one risk of flying long distances is developing DVT (deep vein thrombosis), a blood clotting condition caused by prolonged inactivity. To prevent this, take every opportunity to stretch your legs and walk around the cabin. Compression tights and socks are another easy way to help reduce this risk.

How to get through airport security fast when flying to Flat River?
A little pre-planning before you arrive at the airport can make your trip to Flat River a pleasure. Here are some useful tips for a stress-free journey past security:

  • Keep your travel documents and ID at hand. They're the first items you'll be asked to show at security.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All your electronic gadgets, including your laptop and phone, will also need to be scanned separately.
  • Can't travel without your favourite hand cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, you're allowed to bring it with you in your carry-on.
  • There's a good chance you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a clever idea.
  • Sharp items are not allowed on board. They'll be confiscated at security, so pack them in your checked bags.
