Cheap Flights to Portsmouth from HK$3,857

Depending on where you're coming from, your flight to Portsmouth could be simple and straightforward or it could go on forever. We've pulled together some handy travel tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

• It's simple — first, pack in your passport, travel docs, credit cards and daily medications. Next, you'll need some in-flight entertainment to while away the hours. A thrilling book and a tablet filled with your favourite shows are some great options. If you hope to catch a few z's, a neck pillow and some earplugs will also be useful. Finally, make room for a toothbrush and some deodorant to ensure you touchdown looking and feeling fresh.

Do not pack the following items in your hand luggage:

• While the list of restricted items differs between air carriers, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes box cutters, razor blades, spray paint and flares. Sporting equipment like baseball bats, 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:

• Comfort should be your main concern when deciding what to wear during your flight. Loose, breathable clothing is a smart choice, as are flat, closed-toe shoes.
• Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged 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.

Being prepared before your flight will make your getaway to Portsmouth quick and painless. We've compiled some top tips for a stress-free journey through security:

• Be sure to keep your ID and boarding pass someplace easily accessible. They'll be the first things you'll be asked for by security.
• Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the 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.
• All electronic devices, including your tablet and phone, will also need to be scanned.
• Travelling with your favourite perfume? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're permitted to bring it with you on board.
• Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when going through security. Big boots and other heavy-style shoes are often subjected to extra screening.
• Airlines won't allow any sharp or pointed objects in your carry-on luggage. If you must bring these kinds of items, pack them safely in your checked luggage.
