We've rounded up all the info you need to make your flight a stress-free experience. Follow our insider tips and you'll be hightailing it through the airport and discovering Princeton in next to no time. What to pack in your hand luggage:

• The trick to having an awesome flight experience is to plan ahead. First up, the essentials: passport, travel documents, bank cards and medications. Next, bring items that'll help keep you entertained, like some electronic devices or a thrilling novel. It's also wise to pack your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. Finally, be sure to pop in toiletries like a toothbrush, cleansing wipes and a clean T-shirt.

Do not pack the following items in your hand luggage:

• Make sure you don't have a Swiss Army knife hiding in one of the zippers of your carry-on luggage. Other prohibited items include flammable or explosive substances, such as aerosol cans and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• You'll want to choose comfort over style. Prepare for changes in cabin temperature by wearing layers, and opt for flat, easy-to-remove shoes like slip-ons.
• Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clotting due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

The answer is simple — be prepared. We've rounded up some handy tips and tricks for a fuss-free trip through security. Watch out Princeton, here you come:

• Keep your passport and boarding pass close by. They'll be the first things you'll be asked to show at airport security.
• The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
• For just a few moments, you'll need to unplug from the digital world. Your phone, tablet and any other electronic devices will need to be sent through the scanner.
• Any liquids or gels, such as perfume or toothpaste, that you want to take on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
• Lightweight sneakers are a clever footwear choice as you're less likely to be required to remove them when going through security. Boots and heavier-style shoes are often subjected to extra screening.
• Sharp or pointed items are prohibited in the cabin. They'll be confiscated at security, so pack them in your checked baggage.
