Cheap Flights to Llanberis from HK$2,919

If you're poorly prepared, travelling can be testing. But there's no need to panic. Follow these handy hints for a hassle-free start to your time in Llanberis. What to pack in your hand luggage:

• First, pack in your passport, important documents, wallet and medications. Next, you'll want some entertainment to while away the hours. A juicy novel and a phone filled with your favourite movies are always good options. If you intend to catch a few z's, a comfy neck pillow and some noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some facial wipes so you'll step off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have sharp objects (like a pocket knife) lurking in the bottom of your carry-on luggage. Other prohibited items include flammable or explosive products, such as aerosol cans and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Choose comfort over style. Prepare for changes in temperature by dressing in layers, and wear flat, slightly roomy footwear like sneakers.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To minimize your risk on board, drink plenty of water, consider wearing compression tights or socks and move your lower limbs often.

The answer is — be prepared. We've rounded up some tips and tricks for a speedy trip through security. Watch out Llanberis, here you come:

• Airport security personnel first need to check that you have a valid passport and travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
• Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
• All electronic gadgets, including your phone and laptop, are also required to be separately scanned.
• Can't travel without your favourite hand and nail cream? Not a problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you in your carry-on baggage.
• There's a good chance you'll be required to take your shoes off for scanning, so wearing lightweight sneakers is always a good idea.
• Airlines won't allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, put them in your checked baggage.
