Cheap Flights to Newark from HK$1,151

If you're poorly prepared, air travel can be testing. But there's no need to worry. Follow these useful tips for a stress-free start to your getaway in Newark. What to pack in your hand luggage:

• The secret to having a worry-free travel experience is to pack in advance. So, let's start with the essentials: passport, travel documents, credit cards and daily medications. Next, bring items that'll help keep you entertained, like some electronic gadgets or a magazine. You'll also want to bring your chargers, a quality neck pillow and a pair of earphones. And of course, don't forget to pop in toiletry items like a toothbrush, facial wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

• While the list of restricted items can differ between airlines, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, knives, fuels and bleaching agents. Sports equipment like ski poles, and items that could harm other people, such as firearms and swords, won't be allowed on board either.

What to wear on a flight:

• Comfort should be your main priority when deciding what to wear during your flight. Loose clothing is a sensible option, as are flat, closed-toe shoes.
• Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

The answer is — be prepared. We've rounded up some handy tips and tricks for a speedy trip through airport security. Look out Newark, here you come:

• Your passport and boarding pass will need to be presented to airport security personnel. Keep them handy so you don't hold up the queue.
• The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
• For just a few minutes, you'll need to unplug from the digital world. Your laptop, phone and any other electronics also need to go through the scanner.
• Don't forget to remove liquids and gels from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
• There's a good chance you'll need to take your shoes off for scanning, so wearing slip-on shoes is always a clever idea.
• Airlines won't allow any sharp objects in your carry-on luggage. If you must bring these kinds of items, check them in.
