Do you have any tips for my flight to Louisiana?
We've pulled together all the info you need to make your journey as pain-free as possible. Follow our tips and you'll be zooming through the airport and having a ball in Louisiana in no time flat. What to pack in your hand luggage:
  • First and foremost, pack your passport, travel docs, bank cards and daily medications. Next, you'll need some in-flight entertainment to help pass the time. A thrilling book and a tablet crammed with your favourite movies are good options. If you hope to catch up on some sleep, a neck pillow and some earplugs will also be useful. Finally, find room for a toothbrush and some cleansing wipes so you'll hop off the plane feeling fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Squeeze all your full-sized bottles of hair gel and hairspray in your checked baggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like your beloved Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, spray paint and poisons, are also not allowed.
What to wear on a flight:
  • The aisles of an airplane aren't the place for a fashion parade. Layer up with comfy clothing and pick shoes that are flat, roomy and easy to pull on and off.
  • Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-distance flights. Lower your risks by staying hydrated, keeping your lower limbs moving and wearing compression socks or tights.
How to get through airport security fast when flying to Louisiana?
As savvy travellers know, the secret is to be well organized before you get to security. That way, you'll be boarding that plane to Louisiana in the blink of an eye. Follow these tips and get your trip off to a great start:
  • Keep your travel documents and passport within easy reach. They'll be the first things you'll be asked to show at airport security.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Items such as your jacket, belt and headphones need to go through the machine.
  • Your electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry though, you'll be back online in no time.
  • Travelling with your favourite hand cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on bag.
  • There's a possibility that you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a wise idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed in the cabin.
