Cheap Flights to Princeton from HK$4,125

If you're poorly prepared, airports and flying can be testing. But don't hit the panic button just yet. Follow these helpful hints for a stress-free start to your getaway in Princeton. What to pack in your hand luggage:

• It's simple — first, put in your passport, official ID, cash and daily medications. Next, you'll need some entertainment to while away the time. A juicy book and a laptop crammed with your favourite shows are good options. If you plan to catch up on some sleep, a neck pillow and some noise-cancelling headphones will also be useful. Finally, leave space for a toothbrush and some facial wipes so you'll touchdown feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp or pointed objects, like your treasured Swiss Army knife, and dangerous goods which are flammable or explosive, such as flares, bleaching agents and fuels, are also not allowed.

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for temperature changes in the cabin by wearing layers, and pick closed-toe, flat shoes like slip-ons.
• Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To lessen your risk on board, drink lots of water, consider wearing compression socks or tights and keep your legs and feet moving.

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

• Your passport and travel documents will need to be presented to airport security personnel. Keep them handy so you don't hold up the queue.
• Next up is the X-ray machine. Remove anything metal on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
• Your electronic devices like laptops and phones will also have to go through the machine to be scanned. No need to worry though, you'll be back online soon enough.
• Want to bring along your favourite cologne or perfume? As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on bag.
• Lightweight sneakers are a good footwear choice as you're less likely to be asked to remove them when passing through security. Hiking boots and other bulky shoes are often subjected to additional screening.
• Sharp items such as knives and scissors are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked baggage.
