Do you have any tips for my flight to Eureka?
Depending on where you're coming from, your journey to Eureka could be no sweat at all or it could go on forever. We've rounded up some tips that will help you start your next big adventure on a positive note. What to pack in your hand luggage:

  • The trick to having an awesome flight experience is to be prepared. So, let's start with the basics: passport, official ID, cash and important medications. Next, take on board items that'll help keep you occupied, like your laptop or a magazine. It's also smart to bring your chargers, a comfy neck pillow and a pair of headphones. And of course, be sure to pop in toiletries like a toothbrush, deodorant and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a knife or scissors) lurking in one of the zippers of your carry-on luggage. Other restricted items include explosive or flammable substances, such as fuel and fireworks, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your goal here is to feel as comfortable as possible. Go for easy-to-remove footwear, dress in loose, breathable clothing and don't forget to bring a jacket in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Eureka?
The answer is — be prepared. We've pulled together some handy tips and tricks for a hassle-free trip through security. Look out Eureka, here you come:

  • First things first. Your ID and travel documents will need to be inspected by airport security. Keep them someplace accessible so you don't hold up the line.
  • Next up, both you and your carry-on bag must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items like your belt, jacket and headphones need to go through the machine.
  • Electronic devices like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online before you know it.
  • Remember to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a sensible footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other heavy shoes are usually subjected to extra screening.
  • Sharp items such as knives and scissors can't be taken on board. They'll be seized at security, so put them in your checked baggage.
