• The trick to having a pain-free travel experience is to pack in advance. So, let's start with the essentials: passport, travel docs, credit cards and vital medications. Next, take on board items that'll help keep you occupied, like some electronic gadgets or a magazine. You'll also want to pack your chargers, a neck pillow and a pair of noise-canceling headphones. Finally, be sure to toss in toiletries like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have sharp or pointed objects lurking in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive products, like aerosols and matches, and gels and liquids in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The answer to a comfortable flight is often as simple as the clothes you wear. Prepare yourself for varying temperatures by bringing layers. This will keep you nice and warm if the cabin gets chilly. Shoes like high heels and sandals are best left in your suitcase. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
• The result of sustained periods of immobility, deep vein thrombosis (DVT) is a serious condition that can affect some passengers on long-distance flights. The good news is there are ways to reduce your risk of developing it. Stay hydrated, get up and wander the aisles wherever possible and wear compression socks to help improve your circulation.

The secret is to be prepared before you arrive at airport security. That way, you'll be boarding that plane to Londonderry in next to no time. Follow these tips and get your vacation off to a fantastic start:

• First things first. Your boarding pass and travel ID will need to be presented to airport security. Keep them at hand so you don't hold up the queue.
• Next up, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items like your jacket, belt and earphones need to go through the machine.
• For just a few moments, you'll need to unplug from technology. Your tablet, phone and any other electronic gadgets will also need to go through the scanner.
• Traveling with your favorite perfume or cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, it's fine to bring with you in your carry-on bag.
• It's also possible you'll be required to remove your shoes for scanning, so wearing slip-on shoes is always a good 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 luggage. They won't be allowed on board.
