Do you have any tips for my flight to Portmarnock?
Wherever you're coming from, flying can be a pleasant experience if you're well prepared. Follow these handy tips and tricks that will get your Portmarnock vacation started on the right foot. What to pack in your hand luggage:

  • A plane ride can be a comfortable experience if you take the right gear. Firstly, you'll need basic toiletry items, such as a toothbrush and lip balm, a fresh change of clothes and a good book. Next, make room in your carry-on bag for your laptop, a charger, any medications and maybe a comfy neck pillow too. Last, but definitely not least, remember to take your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like your treasured Swiss Army knife, and dangerous products which are explosive or flammable, such as aerosols and poisons, are also not allowed.

What to wear on a flight:

  • Your main priority is to feel as comfortable as you can. Choose a pair of flat, closed-toe shoes, dress in loose, natural fibers and remember to take a jacket in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to Portmarnock?
The secret is to be well organized before you get to security. That way, you'll be stepping onto that plane to Portmarnock before you know it. Follow these helpful tips and get your trip off to a flying start:

  • Keep your passport and boarding pass within easy reach. They'll be the first things you'll be asked to show at airport security.
  • Your coat, belt, keys and other small items, like coins, will be required to go through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
  • For just a few minutes, you'll have to unplug from technology. Your phone, tablet and any other electronic devices also need to go through the scanner.
  • 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, you can bring it with you in your carry-on.
  • The right choice of footwear can save you several valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers are usually not.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board.
