Do you have any tips for my flight to Duncannon?
Depending on where you're coming from, your flight to Duncannon could be completely painless or it could go on forever. We've rounded up some useful tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

  • The trick to having a hassle-free flight experience is to plan ahead. So, let's start with the basics: passport, travel documents, bank cards and daily medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a thrilling novel. It's also wise to pack your chargers, a quality neck pillow and a pair of headphones. Finally, be sure to pop in toiletries like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your treasured Swiss Army knife, and products which are explosive or flammable, such as aerosols and poisons, are also prohibited.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for temperature changes in the cabin by wearing layers, and opt for flat, closed-toe shoes like slip-ons.
  • Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clotting due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to Duncannon?
As seasoned travellers know, the secret is to be organised before you get to airport security. That way, you'll be stepping onto that plane to Duncannon in the blink of an eye. Follow these helpful tips and get your trip off to a terrific start:

  • Airport security personnel first need to check that you have a valid ID and travel documents before you can proceed any further. Have them ready for inspection.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll have to unplug from technology. Your phone, tablet and any other electronic gadgets also need to be sent through the scanner.
  • Remember to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Sharp items like knives are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked bags.
