Do you have any tips for my flight to Pacific?
If you're poorly prepared, airports and flying can be challenging. But there's no need to worry. Follow these handy tips and enjoy a pleasant start to your getaway in Pacific. What to pack in your hand luggage:

  • Travelling on a plane can be a stress-free experience if you bring the right gear. First of all you'll need basic toiletries, such as a toothbrush and some deodorant, a fresh set of clothes and something to read. Secondly, find room in your bag for your electronic gadgets, chargers, medications and perhaps a neck pillow as well. Lastly, be sure to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like your trusty pocket knife, and products which are explosive or flammable, such as flares, chemicals agents and fireworks, are also prohibited.

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear on board. Loose, breathable clothing is a smart choice, as are flat, enclosed shoes.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and move your lower limbs often.

How to get through airport security fast when flying to Pacific?
Being prepared before your flight will help make your getaway to Pacific a piece of cake. Here are some handy tips and tricks for a swift journey past security:

  • Be sure to keep your travel documents and passport at hand. They're the first things you'll be asked for by airport security.
  • Next up, both you and your carry-on bag will be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items such as your belt, jacket and headphones need to go through the machine.
  • Your electronic devices like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online in no time.
  • Remember to remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • 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 luggage. They won't be allowed on board.
