We've rounded up all the info you need to make your flight as pain-free as possible. Follow our insider tips and you'll be breezing through the airport and discovering Oakbrook Terrace before you know it. What to pack in your hand luggage:

• The secret to having a worry-free flight experience is to pack ahead. So, let's start with the essentials: passport, travel docs, cash and vital medications. Next, take on board items that'll help keep you entertained, like your laptop or a few magazines. It's also wise to bring your chargers, a neck pillow and a pair of noise-cancelling headphones. And of course, don't forget to toss in toiletries like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a Swiss Army knife lurking in the bottom of your carry-on luggage. Other prohibited items include explosive or flammable substances, such as bleach and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

• Comfort should be your main concern when deciding what to wear on board. Loose clothing is a wise option, as are flat, enclosed shoes.
• Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

The answer is simple — be prepared. We've compiled some handy tips and tricks for a speedy trip through security. Look out Oakbrook Terrace, here you come:

• Security personnel first need to establish that you have a valid passport and travel documents before you can proceed any further. Keep them close by.
• Next up is the X-ray machine. 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.
• Electronic devices like phones and laptops will also need to go on a tray for inspection. Don't worry though, you'll be back online before you know it.
• Any gels or liquids, such as toothpaste or perfume, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), zip-lock bag.
• There's a chance you'll be asked to remove your shoes for scanning, so wearing slip-on sneakers is always a smart idea.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board and will be confiscated.
