Do you have any tips for my flight to Lake Forest?
Wherever you're coming from, flying can be a seamless experience if you're prepared. We've put together a list of essential travel tips that will get your Lake Forest escape started on the right note. What to pack in your hand luggage:
  • First things first, put in your passport, travel documents, cash and vital medications. Next, you'll want some entertainment to while away the time. A thrilling book and a laptop filled with your favourite movies are some fantastic options. If you intend to take a quick nap, a quality neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, squeeze in a toothbrush and some deodorant to ensure you step off the plane looking fresh and ready to go.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items can differ between airlines, the general rule of thumb is nothing sharp, flammable or explosive. This includes things like box cutters, razor blades, fuels and bleaching agents. Sporting equipment like bows and arrows, and items that could injure passengers, such as firearms and ammunition, are also banned from the cabin.
What to wear on a flight:
  • Your top priority is to be as comfortable as you can. Pick a pair of slip-on shoes, dress in loose, breathable clothing and remember to bring a pullover in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.
How to get through airport security fast when flying to Lake Forest?
Being organised before you get to the airport will help make your trip to Lake Forest easy and painless. Here are some top tips for a swift journey through security:
  • First things first. Your passport and travel documents will need to be shown to security personnel. Have them easily accessible so you don't have to dig around for them.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Personal belongings such as your belt, jacket and earphones will be required to go through the machine.
  • Your electronic devices like phones and laptops will also have to go on a tray to be scanned. Don't worry though, you'll be back online in no time.
  • Can't travel without your favourite perfume or cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you're allowed to bring it with you in your carry-on luggage.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and heavier-style shoes are often subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed in the cabin.
