How to survive the flight to Lake Forest?
We've rounded up all the info you need to make your journey as enjoyable as possible. Follow our tips and tricks and you'll be cruising through airport security and discovering Lake Forest before you know it.What to pack in your hand luggage:

  • Firstly, and most importantly, pack in your passport, travel documents, bank cards and medications. Next, you'll want some entertainment to help pass the time. A thrilling novel and a tablet filled with your favourite shows are some fantastic options. If you intend to take a short nap, a comfy neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some deodorant to ensure you hop off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a pocket knife) lurking in your carry-on luggage. Other banned items include explosive or flammable substances, such as bleach and fuel, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The aisles of a plane are not the place for a fashion parade. Wear comfortable clothes and don't forget to bring a cardigan as it tends to get cool inside the cabin during long-haul flights. Enclosed, flat shoes are always a good choice too.
  • The serious condition called deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clots forming due to poor circulation and inactivity. Walking around the cabin and doing regular leg and foot exercises in your seat helps to prevent this developing. Wearing a pair of compression socks or tights is also a wise idea.

How to get through airport security fast when flying to Lake Forest?
The trick is to be well prepared before you reach airport security. That way, you'll be stepping onto that plane to Lake Forest in no time flat. Follow these helpful tips and get your holiday off to a spectacular start:

  • Your travel documents and ID will need to be inspected by security personnel. Have them easily accessible so you don't hold up the line.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Items like your jacket, belt and headphones need to go through the machine.
  • Your electronic devices like laptops and phones will also need to go on a tray for inspection. No need to worry though, you'll be back online before you know it.
  • Remove all liquids and gels from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each item 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-close bag.
  • There's a good chance you'll be required to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a smart idea.
  • Airlines won't allow any sharp or pointed objects to come on board with you. If you need to bring these kinds of items, put them in your checked luggage.
