Cheap Flights to Herndon from HK$1,544

Depending on where you're coming from, your trip to Herndon could be completely stress-free or it could go on forever. Below are some handy travel tips that will help you start your unforgettable escape on a positive note. What to pack in your hand luggage:

• The trick to having a worry-free travel experience is to plan ahead. First up, the essentials: passport, travel docs, bank cards and daily medications. Next, take on board items that'll help keep you busy, like some electronic gadgets or a magazine. It's also wise to pack your chargers, a neck pillow and a pair of headphones. Finally, be sure to squeeze in toiletries like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

• While the list of banned items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes screwdrivers, knives, fuel and fireworks. Sporting equipment like baseball bats, and objects that could injure passengers, such as firearms and swords, aren't allowed in the cabin either.

What to wear on a flight:

• Comfort should be your number one priority when deciding what to wear during your flight. Loose clothing is a wise choice, as are roomy, closed-toe shoes.
• Deep vein thrombosis (DVT), a blood clotting condition caused by extended 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.

As seasoned travellers know, the secret is to be prepared before you reach security. That way, you'll be hopping onto that plane to Herndon in a flash. Follow these tips and get your trip off to a great start:

• Airport security personnel first need to determine that you have a valid ID and matching boarding pass before you can proceed any further. Have them in your hand, ready for inspection.
• Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like coins, will be required to go through the X-ray machine. Make your life easier by removing them before your turn arrives.
• Electronic devices like laptops and phones will also have to go through the machine for inspection. Don't worry, you'll be back online before you know it.
• Can't travel without your favourite perfume? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can bring it with you in your carry-on baggage.
• There's a possibility that you'll be required to remove your shoes for scanning, so wearing lightweight sneakers is always a clever idea.
• Airlines will not allow any pocket knives or other sharp items in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked baggage.
