Cheap Flights to Portsmouth from HK$3,733

We've got the lowdown on how to make your flight as stress-free as possible. Follow our tips and you'll be breezing through the airport and seeing the best of Portsmouth in next to no time. What to pack in your hand luggage:

• Firstly, and most importantly, put in your passport, important documents, credit cards and daily medications. Next, you'll want some in-flight entertainment to while away the hours. A thrilling novel and a tablet filled with your favourite shows are good options. If you hope to catch more than just forty winks, a quality neck pillow and some earplugs will also come in handy. Finally, squeeze in a few toiletry items so you'll hop off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and conditioner in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your precious pocket knife, and dangerous goods which are flammable or explosive, such as flares, chemicals agents and poisons, are also not allowed.

What to wear on a flight:

• Your top priority is to be as comfortable as you can. Pick slip-on footwear, dress in loose, natural fibers and don't forget to bring a sweater in case you get chilly in the cabin.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged 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 improve your circulation.

Being organised before you arrive at the airport will make your getaway to Portsmouth a pleasure. We've rounded up some useful tips for a stress-free journey past security:

• Security personnel first need to determine that you have a valid ID and matching travel documents before anything else. Have them in your hand, ready for inspection.
• Time to strip down. Well sort of. Your coat, belt, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them before your turn.
• Your electronic devices like phones and laptops will also need to go on a tray for inspection. Don't worry, you'll be back online before you know it.
• Want to bring along your favourite perfume or cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's OK to bring with you on board.
• There's a chance you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a smart idea.
• Sharp items such as knives and scissors are prohibited in the cabin. They'll be seized at security, so pack them safely away in your checked bags.
