Do you have any tips for my flight to Greencastle?
If you're poorly prepared, air travel can be daunting. But don't hit the panic button just yet. Follow these tips and tricks for a pleasant start to your getaway in Greencastle. What to pack in your hand luggage:
  • First, put in your passport, travel docs, credit cards and medications. Next, you'll want some entertainment to while away the hours. A juicy novel and a tablet crammed with your favourite movies are some terrific options. If you hope to catch forty winks, a comfy neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, find room for a toothbrush and some cleansing wipes to ensure you arrive at your destination looking fresh and ready to go.
Do not pack the following items in your hand luggage:
  • While the list of restricted items can differ between airlines, the general guide to follow is nothing flammable, sharp or explosive. This includes screwdrivers, knives, aerosol cans and flares. Sports equipment like ski poles, and items that could harm other people, such as firearms and ammunition, won't be allowed on board either.
What to wear on a flight:
  • The aisles of a plane aren't the place for a fashion parade. Wear layers and opt for shoes that are roomy, flat and easy to take on and off.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To reduce your risk on board, drink lots of water, consider wearing compression socks or tights and move your legs and feet often.
How to get through airport security fast when flying to Greencastle?
Being organized before your flight will help make your getaway to Greencastle quick and painless. We've rounded up some useful tips and tricks for a stress-free journey past security:
  • First things first. Your boarding pass and travel ID will need to be presented to airport security personnel. Keep them handy so you don't hold up the line.
  • The X-ray machine comes 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 bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Your electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Don't forget to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner 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.
  • It's also likely that you'll need to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed on board and will be confiscated.
