We've pulled together all the info you need to make your journey as stress-free as possible. Follow our top tips and you'll be cruising through airport security and enjoying Knebworth in no time. What to pack in your hand luggage:

• Air travel can be a pleasure if you take the right things. First of all you'll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a spare change of clothes and a good novel. Next, find room in your bag for your electronic devices, chargers, medications and maybe a proper neck pillow as well. Lastly, and most importantly, don't forget to take your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

• While the list of restricted items can differ between air carriers, the general guide to follow is nothing sharp, flammable or explosive. This includes things like screwdrivers, drills, fuels and bleaching agents. Sports equipment like golf clubs, and objects that could injure passengers, such as firearms and ammunition, aren't allowed in the cabin either.

What to wear on a flight:

• The aisles of an airplane are no place for a fashion parade. Wear layers and choose shoes that are enclosed, flat and easy to slip on and off.
• Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Lower your risks by drinking water, keeping your lower limbs moving and wearing compression tights or socks.

It's all about being prepared. We've put together some useful tips for a speedy trip through airport security. Look out Knebworth, here you come:

• Security personnel first need to establish that you have a valid ID and boarding pass before anything else. Keep them close by.
• Time to strip down. Well kind of. Your jacket, belt, keys and other items in your pocket, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
• All your electronics, including your laptop and phone, are also required to be scanned separately.
• Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
• Choosing your footwear wisely can save you a few precious minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers are usually not.
• Pocket knives and other sharp items are not allowed in the cabin. They'll be seized at security, so pack them safely away in your checked bags.
