Cheap Flights to Waltham from HK$5,425

Depending on where you're coming from, your flight to Waltham could be completely painless or it could go on forever. We've rounded up some handy tips that will help you start your next big adventure on the right foot.What to pack in your hand luggage:

• A plane ride can be a pleasure if you've got all the right gear. First of all you'll need basic toiletries, such as deodorant, toothpaste and a toothbrush, a fresh set of clothes and a magazine or two. Next, leave space in your bag for your mobile phone, a charger, any vital medications and perhaps a proper neck pillow too. Lastly, be sure to bring your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

• Put 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) won't be allowed on. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous products which are explosive or flammable, such as spray paint, flares and strong acids, are also banned.

What to wear on a flight:

• Your number one priority is to make yourself as comfortable as possible. Dress in loose, natural-fiber clothing and remember to bring a sweater in case you get cold. Go for a pair of flat, well-fitting shoes as it's possible that your feet and ankles will swell during the flight. Leave the stilettos and chunky boots in your luggage.
• Most travelers are aware of DVT (deep vein thrombosis), a blood clot condition caused by long periods of sitting. There are numerous ways to lower your risk. Wear a good-quality pair of compression tights or socks, stay hydrated and remember to keep your legs and feet moving. Walk the aisles of the cabin or perform some stretches in your seat.

Being prepared before you get to the airport will help make your trip to Waltham a pleasure. Here are some useful tips for a speedy journey past security:

• Airport security personnel first need to determine that you have a valid ID and travel documents before anything else. Have them close by, ready for inspection.
• Time to strip down. Well kind of. Your belt, jacket, keys and other items in your pocket, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
• For just a few minutes, you'll have to unplug from the digital world. Your tablet, phone and any other electronic gadgets must also go through the scanner.
• Any liquids or gels, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one liter), clear zip-close bag.
• There's a chance you'll be asked to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a wise idea.
• Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won't be allowed on board and will be confiscated.
