• The secret to having a great flight experience is to plan ahead. Start with the essentials: passport, travel documents, bank cards and any vital medications. Next, bring on board items that'll help keep you occupied, like some electronic gadgets or a magazine. It's also a wise idea to pack your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to chuck in toiletries like a toothbrush, lip balm and a clean set of clothes.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a Swiss Army knife lurking in one of the zippers of your carry-on luggage. Other restricted items include explosive or flammable products, such as bleach and fuel, 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 top priority when choosing what to wear during your flight. Loose, breathable clothing is a wise choice, as are enclosed shoes like sneakers.
• Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To reduce your risk on board, stay hydrated, consider wearing compression socks or tights and keep your legs and feet moving.

The simple answer is — be prepared. We've put together some top tips for a hassle-free trip through airport security. Watch out Londonderry, here you come:

• Be sure to keep your ID and boarding pass someplace easily accessible. They'll be the first things you'll be asked for by security.
• Next up, both you and your carry-on bag will be X-rayed. To speed things up, remove anything that is likely to set the alarm off. Personal belongings like your belt, coat and earphones will be required to go through the machine.
• All your electronic gadgets, including your phone and tablet, will also need to be scanned separately.
• Any liquids or gels, such as hair oil or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
• It's also possible you'll need to remove your shoes for scanning, so wearing slip-on shoes is always a wise idea.
• Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you must bring these kinds of items, pack them in your checked luggage.
