How to survive the flight to Effingham?
Depending on where you’re coming from, your journey to Effingham could be completely painless or it could go on forever. We’ve compiled some handy travel 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 carry the right stuff. First of all you’ll need basic toiletries, such as a toothbrush and hairbrush, a clean pair of socks and a few magazines. Secondly, leave space in your carry-on bag for your mobile phone, a charger, any vital medications and maybe a blow-up neck pillow too. Lastly, and most importantly, be sure to take your passport, travel docs and your credit cards.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Pointed or sharp objects, like a Swiss Army knife, and dangerous products which are flammable or explosive, such as spray paint, flares and gasoline, are also banned.

What to wear on a flight:

  • The aisles of your plane are no place for a fashion parade. Layer up with comfy clothing and remember to bring a cardigan as the temperature can drop in the cabin during long-haul flights. Enclosed, flat shoes are also a good choice.
  • Unfortunately, one risk of long-distance travel is developing DVT (deep vein thrombosis), a blood clotting condition caused by lengthy periods of inactivity. To avoid this, make the most of every opportunity to stretch your legs and walk around the cabin. Compression tights and socks are another simple way to help reduce this risk.

How to get through airport security fast when flying to Effingham?
As seasoned travellers know, the secret is to be organised before you reach the security gate. That way, you’ll be boarding that plane to Effingham in no time flat. Follow these tips and get your holiday off to a fantastic start:

  • Your passport and travel documents will need to be shown to airport security. Keep them handy so you don’t have to dig around for them.
  • Your belt, jacket, keys and other contents of your pockets, like your earphones, will be required to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • Electronic devices like phones and laptops will also have to go on a tray for inspection. No need to worry though, you’ll be back online soon enough.
  • Can’t travel without your favourite hand cream? No problem. As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a clear zip-close bag, you can bring it with you on board.
  • Slip-on shoes are a great footwear choice as you’re less likely to be required to remove them when going through security. Big boots and other bulky shoes are often subjected to extra screening.
  • Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They’ll be seized at security, so pack them safely away in your checked luggage.
