Cheap Flights to Watford from HK$669

Wherever you're jetting in from, flying can be a pleasant experience if you're well organised. We've compiled a list of handy tips that will get your Watford holiday started on the right note. What to pack in your hand luggage:

• First of all, pack your passport, travel documents, credit cards and vital medications. Next, you'll need some entertainment to help pass the time. A thrilling book and a laptop crammed with your favourite shows are some great options. If you intend to take a short nap, a comfy neck pillow and some earplugs will also be useful. Finally, make room for a toothbrush and some deodorant so you'll step off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

• Double-check that you don't have a Swiss Army knife lurking in one of the compartments of your carry-on luggage. Other banned items include flammable or explosive products, like aerosols and matches, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• The aisles of a plane aren't the place for a fashion parade. Don comfortable layers and pick shoes that are flat, enclosed and easy to take on and off.
• Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation.

A little pre-planning before your flight will make your trip to Watford a pleasure. Here are some handy tips for a swift journey through security:

• Have your travel documents and passport handy. They're the first items you'll be asked to present to security.
• The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
• Your electronic devices like laptops and phones will also have to go through the machine for inspection. Don't worry though, you'll be back online soon enough.
• Remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
• Choosing your footwear wisely can save you valuable minutes. Hiking boots are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
• Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you must bring these kinds of items, put them in your checked baggage.
