Do you have any tips for my flight to Letterkenny?
If you're poorly prepared, travelling can be tough. But don't hit the panic button just yet. Follow these tips and tricks and enjoy a stress-free start to your time in Letterkenny. What to pack in your hand luggage:

  • It's easy — first, put in your passport, travel documents, wallet and vital medications. Next, you'll need some entertainment to while away the time. A thrilling book and a phone crammed with your favourite shows are some great options. If you intend to catch more than just forty winks, a quality neck pillow and a pair of earplugs will also be useful. Finally, find room for a toothbrush and some facial wipes so you'll hop off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, pocket knives, aerosol cans and bleaching agents. Sporting equipment like golf clubs, and items that could injure passengers, such as guns and swords, aren't allowed in the cabin either.

What to wear on a flight:

  • Comfort should be your number one priority when choosing what to wear on your flight. Loose, breathable clothing is a smart option, as are enclosed shoes like sneakers.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Reduce the risks by drinking water, keeping your legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Letterkenny?
It's all about being prepared. We've compiled some handy tips and tricks for a stress-free trip through security. Look out Letterkenny, here you come:

  • Keep your boarding pass and passport easily accessible. They'll be the first things you'll be asked for by airport security.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to beep. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All your electronics, including your phone and laptop, must also be scanned.
  • Can't travel without your favourite perfume or cologne? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you're permitted to bring it with you in your carry-on bag.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed on board.
