Do you have any tips for my flight to Dundalk?
If you're poorly prepared, travelling can be challenging. But there's no need to worry. Follow these useful tips and enjoy a stress-free start to your time in Dundalk. What to pack in your hand luggage:

  • A plane ride can be a stress-free experience if you've got all the right things. First things first, you'll need toiletry items, such as deodorant and a toothbrush, a spare set of clothes and a few magazines. Secondly, find room in your carry-on bag for your electronic devices, chargers, any daily medications and maybe a quality neck pillow too. Lastly, and most importantly, don't forget to take your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your beloved pocket knife, and dangerous goods which are flammable or explosive, such as flares, chemicals agents and fuels, are also not allowed.

What to wear on a flight:

  • Your aim here is to be as comfortable as possible. Pick flat, closed-toe shoes, dress in loose, natural-fibre clothing and don't forget to take a sweater in case you get chilly in the cabin.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lower your risk on board, stay hydrated, consider wearing compression socks or tights and keep your feet and legs moving.

How to get through airport security fast when flying to Dundalk?
As savvy travellers know, the secret is to be organised before you get to the airport security gate. That way, you'll be stepping onto that plane to Dundalk in a flash. Follow these helpful tips and get your trip off to a fantastic start:

  • First things first. Your ID and travel documents will need to be presented to security personnel. Keep them someplace accessible so you don't hold up the queue.
  • 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 your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • Electronic devices like phones and laptops will also have to go through the machine for inspection. Don't worry though, you'll be back online in no time.
  • Any gels or liquids, such as perfume or hairspray, that you want to bring on board must be no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several valuable minutes. Boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Knives and other sharp items are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked suitcase.
