Cheap Flights to London Colney from HK$2,152

If you're not prepared, travelling can be a real challenge. But don't hit the panic button just yet. Follow these handy tips and enjoy a worry-free start to your holiday in London Colney. What to pack in your hand luggage:

• The secret to having a hassle-free travel experience is to pack ahead. Start with the essentials: passport, travel docs, cash and vital medications. Next, take on board items that'll help keep you busy, like your laptop or a thrilling novel. It's also a wise idea to pack your chargers, a quality neck pillow and a pair of earplugs. Finally, don't forget to pop in toiletries like a toothbrush, cleansing wipes and a fresh change of clothes.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of shampoo and conditioner in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like your beloved pocket knife, and dangerous goods which are explosive or flammable, such as aerosols and matches, are also restricted.

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 flat, enclosed and easy to take on and off.
• Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

Being organised before you get to the airport will help make your trip to London Colney a pleasure. Below are some handy tips and tricks for a swift journey through security:

• Have your passport and travel documents easily accessible. They'll be the first things you'll be asked to show at security.
• After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Personal belongings such as your belt, coat and headphones will be required to go through the machine.
• For just a few minutes, you'll need to unplug from technology. Your laptop, phone and any other electronic gadgets also need to be sent through the scanner.
• Remove gels and liquids from your hand luggage. They often need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
• Slip-on shoes are a good footwear choice as you're less likely to be required to remove them when going through security. Big boots and heavier-style shoes are often subjected to extra screening.
• Pocket knives and other sharp items are prohibited in the cabin. They'll be seized at security, so put them in your checked baggage.
