Cheap Flights to Princeton from HK$5,015

No matter where you're coming from, flying can be a seamless experience if you're well prepared. We've put together a list of essential travel tips that will help get your Princeton escape started on the right note.What to pack in your hand luggage:

• Air travel can be a pleasure if you bring the right stuff. Firstly, you'll need basic toiletries, such as lip balm and hand cream, a spare set of clothes and a magazine or two. Next, find a spot in your hand luggage for your electronic gadgets, chargers, your important medications and perhaps a proper neck pillow too. Lastly, be sure to take your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

• While the list of restricted items differs between air carriers, the general rule of thumb is nothing sharp, flammable or explosive. This includes tools, metal cutlery, aerosol cans and bleaching agents. Sporting equipment like golf clubs, and objects that could harm other people, such as guns and swords, are also banned from the cabin.

What to wear on a flight:

• The narrow aisles of your plane are not the place for a fashion parade. Wear comfortable clothes and take a cardigan as it tends to get cool inside the cabin during longer flights. Flat, slightly roomy shoes are always a good idea too.
• The condition known as DVT (deep vein thrombosis) is a potential risk on long-haul flights. It's the result of blood clotting due to poor circulation. Walking up and down the aisle and doing foot and leg exercises in your seat helps to prevent this developing. Wearing a good pair of compression socks or tights also helps reduce your risk.

The trick is to be prepared before you get to security. That way, you'll be hopping onto that plane to Princeton in no time flat. Follow these tips and get your trip off to a spectacular start:

• Your passport and boarding pass will need to be presented to airport security personnel. Have them close by so you don't have to dig around for them.
• After that, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Personal belongings such as your belt, coat and earphones will be required to go through the machine.
• For just a few moments, you'll need to unplug from the digital world. Your laptop, phone and any other electronic gadgets also need to be sent through the scanner.
• Want to bring along your favorite cologne? Not a problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-close bag, you can keep it with you in your carry-on luggage.
• Slip-on shoes are a great footwear choice as you're less likely to be required to remove them when going through security. Boots and other heavy-style shoes are usually subjected to additional screening.
• Pocket knives and other sharp items are prohibited in the cabin. They'll be confiscated at security, so pack them in your checked luggage.
