Do you have any tips for my flight to Lake Forest?
Depending on where you're coming from, your flight to Lake Forest could be as easy as pie or it could go on forever. We've compiled some tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

  • Flying can be a stress-free experience if you've got all the right things. Firstly, you'll want a few toiletry items, such as a toothbrush and hairbrush, a spare set of clothes and a few magazines. Next, find a spot in your bag for your electronic devices, chargers, your important medications and perhaps a comfy neck pillow as well. Lastly, and most importantly, don't forget to take your passport, travel papers and some money.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your beloved pocket knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and gasoline, are also prohibited.

What to wear on a flight:

  • Your aim here is to feel as comfortable as possible. Go for a pair of flat, closed-toe shoes, dress in loose, breathable clothing and remember to take a sweater in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Lake Forest?
A little pre-planning before you arrive at the airport will make your getaway to Lake Forest a pleasure. Below you'll find some useful tips for a speedy journey through security:

  • Be sure to have your boarding pass and ID easily accessible. They're the first items you'll be asked for by security.
  • Your belt, coat, keys and other items in your pocket, like your headphones, will need to go through the X-ray machine. Make your life easier by removing them before your turn arrives.
  • All electronic gadgets, including your phone and laptop, must also be separately scanned.
  • Don't forget to remove gels and liquids from your hand luggage. They often need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • There's a possibility that you'll need to take your shoes off for scanning, so wearing lightweight sneakers is always a good idea.
  • Airlines will not allow any pocket knives or other sharp items in your carry-on luggage. If you must bring these kinds of items, put them in your checked baggage.
