Do you have any tips for my flight to Letterkenny?
Depending on where you're coming from, your trip to Letterkenny could be no sweat at all or it could drag on forever. We've pulled together some handy travel tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

  • A plane ride can be a cruisy experience if you carry the right stuff. Firstly, you'll want a few toiletry items, such as deodorant and a toothbrush, a spare set of clothes and a magazine or two. Secondly, make room in your carry-on bag for your electronic devices, chargers, any vital medications and maybe a blow-up neck pillow too. Lastly, don't forget to take your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like a Swiss Army knife, and dangerous goods which are flammable or explosive, such as flares, bleaching agents and gasoline, are also prohibited.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Layer up with comfortable clothing and opt for shoes that are closed-toe, flat and easy to remove.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lower your risk on board, drink lots of water, consider wearing compression socks and keep your legs and feet moving.

How to get through airport security fast when flying to Letterkenny?
As seasoned travellers know, the secret is to be organised before you arrive at security. That way, you'll be hopping onto that plane to Letterkenny in no time at all. Follow these helpful tips and get your trip off to a terrific start:

  • Security personnel first need to make sure that you have a valid ID and travel documents before anything else. Have them in your hand, ready for inspection.
  • Next up, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that might set the alarms off. Items such as your belt, jacket and earphones will be required to go through the machine.
  • For just a few minutes, you'll have to unplug from the digital world. Your laptop, phone and any other electronic devices must also go through the scanner.
  • Any liquids or gels, such as perfume or toothpaste, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Sharp or pointed items are not allowed on board. They'll be confiscated at security, so pack them in your checked luggage.
