How to survive the flight to Oak Brook?
Wherever you're jetting in from, flying can be a pleasurable experience if you've prepared well. We've made a list of handy tips and tricks that will help get your Oak Brook holiday started on the right note.What to pack in your hand luggage:

  • First of all, put in your passport, travel docs, wallet and daily medications. Next, you'll want some extra in-flight entertainment to while away the time. A thrilling novel and a laptop crammed with your favourite shows are good options. If you plan to take a short nap, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, leave some space for a toothbrush and some deodorant to ensure you arrive at your destination looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp or pointed objects hiding in one of the compartments of your hand luggage. Other banned items include explosive or flammable products, such as bleach and fuel, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The best way to ensure a comfortable flight is often as simple as your clothing choices. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin gets too cold. Shoes like flip flops and heels are best left for other occasions. Even though they may be your favourites, go for flat, closed-toed footwear like sneakers. Your feet will appreciate it.
  • The serious condition called deep vein thrombosis (DVT) can pose a risk on long-distance flights. It's the result of blood clotting due to inactivity and poor circulation. Walking around the cabin and doing regular leg and foot exercises while seated is a great way to prevent this happening. Wearing a good pair of compression tights or socks is also recommended.

How to get through airport security fast when flying to Oak Brook?
Being prepared before you arrive at the airport will help make your trip to Oak Brook a breeze. We've rounded up some useful tips and tricks for a swift journey through security:

  • Be sure to have your travel documents and passport at hand. They're the first items you'll be asked for by security.
  • After that, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might trigger the alarms. Items such as your belt, jacket and headphones will be required to go through the machine.
  • All electronic gadgets, including your tablet and phone, will also need to be separately scanned.
  • Remember to remove gels and liquids from your carry-on bag. 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 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Boots and bulky shoes are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked baggage. They won't be allowed in the cabin.
