Do you have any tips for my flight to The Plains?
If you're poorly prepared, air travel can be daunting. But there's no need to panic. Follow these useful tips for a worry-free start to your getaway in The Plains. What to pack in your hand luggage:

  • The secret to having an awesome flight experience is to pack in advance. Start with the essentials: passport, travel docs, credit cards and any vital medications. Next, take on board items that'll help while away those hours, like some electronic devices or a good book. It's also smart to bring your chargers, a quality neck pillow and a pair of earplugs. And of course, be sure to pop in toiletries like a toothbrush, facial wipes and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes knives, scissors, fuel and fireworks. Sports equipment like baseball bats, and objects that could harm passengers, such as firearms and swords, are also banned from the cabin.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for temperature changes in the cabin by donning layers, and pick flat, enclosed shoes like slip-ons.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to The Plains?
A little pre-planning before you arrive at the airport can make your getaway to The Plains a pleasure. Below are some handy hints for a speedy journey past security:

  • Be sure to keep your boarding pass and ID at hand. They're the first things you'll be asked for by airport security.
  • The X-ray machine is up next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • Your electronic devices like laptops and phones will also have to go through the machine to be scanned. Don't worry though, you'll be back online before you know it.
  • Travelling with your favourite cologne or perfume? 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, it's fine to bring with you in your carry-on bag.
  • Choosing your footwear wisely can save you a few precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
  • Airlines won't allow any sharp items or pocket knives in your carry-on baggage. If you need to bring these kinds of items, put them in your checked luggage.
