Do you have any tips for my flight to Seaside?
We've got the lowdown on how to make your journey as pain-free as possible. Follow our top tips and you'll be speeding through the airport and exploring Seaside before you know it. What to pack in your hand luggage:

  • First, put in your passport, travel docs, wallet and medications. Next, you'll want some in-flight entertainment to help pass the time. A thrilling book and a tablet filled with your favourite shows are some great options. If you intend to take a short snooze, a quality neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave space for a toothbrush and some cleansing wipes to ensure you arrive feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between airlines, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, blades, fireworks and fuel. Sporting equipment like hockey sticks, and items that could harm other people, such as firearms and ammunition, are also banned from the cabin.

What to wear on a flight:

  • Comfort should be your priority when choosing what to wear on board. Loose clothing is a sensible option, as are enclosed shoes like sneakers.
  • You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lessen your risk on board, drink lots of water, consider wearing compression tights or socks and move your lower limbs often.

How to get through airport security fast when flying to Seaside?
As seasoned travellers know, the secret is to be well prepared before you reach the airport security gate. That way, you'll be hopping onto that plane to Seaside in next to no time. Follow these tips and get your trip off to a great start:

  • Your ID and travel documents will need to be inspected by airport security personnel. Have them easily accessible to avoid fumbling around for them.
  • Next up, both you and your hand luggage must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items such as your belt, jacket and headphones will be required to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go on a tray for inspection. No need to worry though, you'll be back online before you know it.
  • Travelling with your favourite hand cream? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's OK to bring with you in your carry-on bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when passing through security. Big boots and other heavy shoes are usually subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed on board and will be confiscated.
