Flights to Smithstown, County Meath from NT$4,480

If you're not prepared, airports and flying can be challenging. But there's no need to worry. Follow these tips and tricks and enjoy a pleasant start to your vacation in Smithstown. What to pack in your hand luggage:

• The secret to having a worry-free flight experience is to pack in advance. First up, the essentials: passport, travel documents, cash and medications. Next, take on board items that'll help while away those hours, like your laptop or a thrilling book. It's also smart to bring your chargers, a neck pillow and a pair of noise-canceling headphones. Last but not least, don't forget to pop in toiletries like a toothbrush, deodorant 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 luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) won't be allowed on. Sharp or pointed objects, like your beloved Swiss Army knife, and products which are explosive or flammable, such as flares, bleaching agents and matches, are also not allowed.

What to wear on a flight:

• Your aim here is to be as comfortable as possible. Go for a pair of slip-on shoes, dress in loose, natural-fiber clothing and remember to bring a sweater in case you get chilly in the cabin.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to promote better circulation.

Being organized before you arrive at the airport will help make your trip to Smithstown a breeze. We've rounded up some useful tips and tricks for a speedy journey past security:

• First things first. Your passport and boarding pass will need to be presented to security personnel. Have them close by so you don't hold up the queue.
• Time to strip down. Well sort of. Your jacket, belt, keys and other items in your pocket, like coins, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn.
• All your electronic devices, including your tablet and phone, will also need to be scanned separately.
• Any gels or liquids, such as perfume or hairspray, that you want to take on board need to be in containers no larger than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-close bag.
• There's a good chance you'll be asked to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a wise idea.
• Airlines will not allow any sharp items or pocket knives in your carry-on baggage. If you must bring these kinds of items, put them in your checked luggage.
