Cheap Flights to Chicago from HK$3,462

Depending on where you're coming from, your trip to Chicago could be simple and straightforward or it could go on forever. We've put together some handy tips that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

• It's simple — first, pack your passport, travel documents, wallet and daily medications. Next, you'll need some in-flight entertainment to while away the hours. A thrilling book and a laptop filled with your favourite shows are some wonderful options. If you intend to take a quick nap, a neck pillow and a pair of earplugs will also be useful. Finally, leave some space for a few toiletry items to ensure you touchdown feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp or pointed objects, like a Swiss Army knife, and dangerous products which are explosive or flammable, such as spray paint, flares and fireworks, are also restricted.

What to wear on a flight:

• Choose comfort over style. Prepare for changes in temperature by donning layers, and opt for flat, enclosed shoes like sneakers.
• Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To reduce your risk on board, stay hydrated, consider wearing compression socks and move your lower limbs often.

The secret is to be well prepared before you arrive at airport security. That way, you'll be boarding that plane to Chicago in a flash. Follow these helpful tips and get your holiday off to a fantastic start:

• First things first. Your passport and boarding pass will need to be shown to airport security personnel. Keep them at hand so you don't have to dig around for them.
• Your belt, jacket, keys and other small items, like your headphones, will need to go through the X-ray machine. Make the whole process faster by removing them as your turn draws near.
• For just a few moments, you'll need to unplug from the digital world. Your phone, laptop and any other electronic gadgets will need to go through the scanner.
• Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
• The right choice of footwear can save you several minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
• Airlines will not allow any sharp objects to come on board with you. If you must bring these kinds of items, check them in.
