If you're not prepared, travelling can be testing. But there's no need to panic. Follow these tips and tricks for a comfortable start to your getaway in Letchworth. What to pack in your hand luggage:

• The trick to having an amazing travel experience is to plan ahead. Start with the essentials: passport, travel docs, credit cards and medications. Next, bring items that'll help keep you occupied, like some electronic devices or a thrilling novel. It's also a wise idea to bring your chargers, a quality neck pillow and a pair of headphones. Finally, don't forget to pop in toiletry items like a toothbrush, cleansing wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

• While the list of banned items differs between airlines, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes things like screwdrivers, knives, spray paint and flares. Sporting equipment like ski poles, and items that could injure passengers, such as guns and swords, can't come on board with you either.

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for temperature changes in the cabin by dressing in layers, and opt for easy-to-remove shoes like sneakers.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of 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.

It's easy — be prepared. We've pulled together some handy tips and tricks for a speedy trip through airport security. Watch out Letchworth, here you come:

• Be sure to keep your travel documents and passport within close reach. They're the first items you'll be asked for by airport security.
• After that, both you and your hand luggage must be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Items like your belt, coat and headphones need to go through the machine.
• Your electronic gadgets like phones and laptops will also have to go on a tray for inspection. Don't worry though, you'll be back online before you know it.
• Can't travel without your favourite perfume or cologne? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're allowed to bring it with you in your carry-on bag.
• Choosing your footwear wisely can save you several minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
• Sharp items like knives can't be taken on board. They'll be confiscated at security, so put them in your checked baggage.
