Cheap Flights to Radlett from HK$2,638

If you're not prepared, air travel can be challenging. But there's no need to panic. Follow these handy tips for a stress-free start to your time in Radlett.What to pack in your hand luggage:

• The trick to having a stress-free flight experience is to pack ahead. First up, the essentials: passport, travel docs, cash and important medications. Next, take on board items that'll help keep you entertained, like some electronic devices or a thrilling novel. It's also wise to bring your chargers, a neck pillow and a pair of noise-canceling headphones. And of course, don't forget to chuck in toiletry items like a toothbrush, lip balm and a clean set of clothes.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp objects, like your precious Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, flares and gasoline, are also banned.

What to wear on a flight:

• Comfort really should be your highest priority when selecting what to wear on your flight. Consider your footwear carefully too, as swollen feet are quite common. Slightly roomy, flat shoes are your best bet.
• A serious condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clotting due to poor circulation and inactivity. Walking around the cabin and doing regular leg and foot exercises while seated is a great way to prevent this happening. Wearing a pair of compression socks can also help.

The secret is to be well organized before you arrive at the security gate. That way, you'll be stepping onto that plane to Radlett in a flash. Follow these helpful tips and get your vacation off to a great start:

• Airport security personnel first need to verify that you have a valid passport and matching travel documents before anything else. Keep them within easy reach.
• Next up, both you and your carry-on bag will be X-rayed. To make the process quick and painless, remove anything that is likely to trigger the alarm. Items like your jacket, belt and headphones will be required to go through the machine.
• Your electronic gadgets like laptops and phones will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
• Don't forget to remove liquids and gels from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-close bag.
• There's a good chance you'll be asked to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a smart idea.
• Sharp items such as knives and scissors can't be taken on board. They'll be confiscated at security, so put them in your checked bags.
