Cheap Flights to London from HK$3,721

Depending on where you're coming from, your flight to London could be a piece of cake or it could drag on forever. Below are some useful travel tips that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:

• The trick to having an awesome travel experience is to be prepared. First up, the essentials: passport, official ID, credit cards and important medications. Next, take on board items that'll help keep you entertained, like some electronic devices or a good book. It's also wise to bring your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Last but not least, be sure to pop in toiletry items like a toothbrush, deodorant and a clean set of clothes.

Do not pack the following items in your hand luggage:

• Make sure you don't have a pocket knife hiding in one of the compartments of your carry-on luggage. Other restricted items include flammable or explosive goods, such as bleach and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Choose comfort over style. Prepare for temperature changes in the cabin by dressing in layers, and wear closed-toe, flat footwear like slip-ons.
• Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some simple exercises in your seat to improve your circulation.

Being prepared before your flight can make your trip to London easy and painless. Below are some handy hints for a stress-free journey through security:

• Have your ID and travel documents within easy reach. They're the first things you'll be asked to present to airport security.
• Next up is the X-ray machine. Empty your pockets and remove anything that is likely to beep. This includes things like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
• All your electronics, including your tablet and phone, will also need to be separately scanned.
• Can't travel without your favourite cologne? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's OK to bring with you in your carry-on baggage.
• Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when passing through security. Big boots and other bulky shoes are often subjected to additional screening.
• Knives and other sharp items are not allowed in the cabin. They'll be seized at security, so pack them in your checked suitcase.
