Do you have any tips for my flight to Castletown-Geoghegan?
We've got the lowdown on how to make your flight an enjoyable experience. Follow our top tips and you'll be cruising through the airport and having a ball in Castletown-Geoghegan in no time flat. What to pack in your hand luggage:

  • First of all, put in your passport, travel documents, bank cards and medications. Next, you'll want some entertainment to help pass the time. A juicy book and a laptop crammed with your favourite shows are always good options. If you hope to take a quick snooze, a neck pillow and a pair of earplugs will also come in handy. Finally, leave some space for a few toiletry items to ensure you touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Pack all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp objects, like your beloved Swiss Army knife, and products which are flammable or explosive, such as flares, chemicals agents and fireworks, are also restricted.

What to wear on a flight:

  • Choose comfort over style. Prepare for changes in temperature by layering up, and opt for flat, enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged 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 promote better circulation.

How to get through airport security fast when flying to Castletown-Geoghegan?
Being organised before you arrive at the airport can make your trip to Castletown-Geoghegan a breeze. Check out our useful tips and tricks for a stress-free journey through security:

  • Airport security personnel first need to determine that you have a valid passport and matching travel documents before you're allowed to proceed any further. Have them ready for inspection.
  • The X-ray machine is up next. Remove anything metal on you that is likely to beep. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
  • All your electronics, including your tablet and phone, must also be scanned.
  • Don't forget to remove liquids and gels from your hand luggage. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • There's a chance you'll be asked to remove your shoes to be X-rayed, so wearing slip-on shoes is always a clever idea.
  • Airlines won't allow any pocket knives or other sharp items to come on board with you. If you must bring these kinds of items, pack them safely in your checked luggage.
