Do you have any tips for my flight to Ireland?
We've rounded up all the info you need to make your journey as stress-free as possible. Follow our tips and you'll be zooming through airport security and having a ball in Ireland in no time flat. What to pack in your hand luggage:

  • A plane trip can be a comfortable experience if you take the right gear. Firstly, you'll want some basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a fresh change of clothes and a magazine or two. Secondly, find a spot in your bag for your mobile phone, a charger, your medications and maybe a comfy neck pillow as well. Lastly, and most importantly, be sure to take your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your treasured pocket knife, and products which are flammable or explosive, such as flares, bleaching agents and gasoline, are also not allowed.

What to wear on a flight:

  • Comfort should be your priority when deciding what to wear on board. Loose clothing is a smart option, as are roomy, closed-toe shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Ireland?
The trick is to be well prepared before you get to the security gate. That way, you'll be hopping onto that plane to Ireland before you know it. Follow these tips and get your trip off to a great start:

  • Be sure to have your boarding pass and passport close by. They'll be the first things you'll be asked to present to security.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the alarm. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll need to unplug from the digital world. Your tablet, phone and any other electronics also need to go through the scanner.
  • Any gels or liquids, such as shampoo or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • It's also likely that you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a wise idea.
  • Sharp items like knives are not allowed in the cabin. They'll be seized at security, so put them in your checked bags.
