Cheap Flights to Greencastle from HK$4,971

We've got the lowdown on how to make your flight as stress-free as possible. Follow our tips and tricks and you'll be speeding through the airport and enjoying Greencastle in no time at all. What to pack in your hand luggage:

• A plane trip can be a stress-free experience if you carry the right stuff. Firstly, you'll need basic toiletry items, such as lip balm and hand cream, a clean set of clothes and a good book. Secondly, leave space in your bag for your phone and charger, any medications and perhaps a blow-up neck pillow as well. Last, but definitely not least, be sure to bring your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

• Double-check that you don't have sharp or pointed objects lurking in your carry-on luggage. Other restricted items include flammable or explosive substances, such as fuel and fireworks, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).

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 flat, roomy and easy to slip on and off.
• Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long flights. Lower your risks by staying hydrated, keeping your ankles and legs moving and wearing compression socks to help your circulation.

Being organised before you get to the airport will help make your getaway to Greencastle a pleasure. Read through our handy tips and tricks for a stress-free journey past security:

• Your passport and travel documents will need to be presented to airport security personnel. Keep them within easy reach so you don't hold up the line.
• Next up is the X-ray machine. Remove anything metal on you that is likely to set off the alarm. 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.
• For just a few minutes, you'll need to unplug from technology. Your phone, tablet and any other electronic devices will also need to be sent through the scanner.
• Travelling with your favourite cologne or perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's fine to bring with you in your carry-on 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.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked suitcase. They won't be allowed on board and will be confiscated.
