Cheap Flights to Castleknock from HK$355

If you're not prepared, airports and flying can be challenging. But don't hit the panic button just yet. Follow these handy tips for a comfortable start to your time in Castleknock. What to pack in your hand luggage:

• The trick to having a great flight experience is to be prepared. So, let's start with the essentials: passport, travel documents, cash and any vital medications. Next, take on board items that'll help while away those hours, like some electronic devices or a thrilling novel. You'll also want to bring your chargers, a comfy neck pillow and a pair of earplugs. Last but not least, be sure to toss in toiletry items like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a sharp object hiding in your hand luggage. Other restricted items include flammable or explosive products, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Comfort should be your main concern when choosing what to wear during your flight. Loose clothing is a sensible option, as are flat, slip-on shoes.
• Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clotting due to inactivity and poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

As seasoned travellers know, the secret is to be organised before you arrive at airport security. That way, you'll be hopping onto that plane to Castleknock in no time flat. Follow these helpful tips and get your trip off to a terrific start:

• Keep your passport and travel documents close by. They'll be the first things you'll be asked for by security.
• After that, both you and your carry-on luggage must be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Personal belongings such as your coat, belt and earphones need to go through the machine.
• All electronic devices, including your laptop and phone, must also be scanned separately.
• Any liquids or gels, such as perfume or toothpaste, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
• Lightweight sneakers are a great footwear choice as you're less likely to have to remove them when passing through security. Hiking boots and heavier-style shoes are often subjected to extra screening.
• Airlines won't allow any sharp items or pocket knives in your carry-on baggage. If you need to bring these kinds of items, put them in your checked luggage.
