Do you have any tips for my flight to Lake Forest?
If you're not prepared, travelling can be a real challenge. But there's no need to hit the panic button just yet. Follow these helpful hints and enjoy a pain-free start to your vacation in Lake Forest. What to pack in your hand luggage:

  • First and foremost, pack in your passport, travel documents, wallet and vital medications. Next, you'll need some extra in-flight entertainment to help pass the time. A thrilling book and a laptop crammed with your favourite shows are some wonderful options. If you plan to catch forty winks, a neck pillow and a pair of earplugs will also be useful. Finally, find room for a toothbrush and some deodorant so you'll touchdown looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have a pocket knife lurking in the bottom of your hand luggage. Other restricted items include explosive or flammable substances, such as aerosol cans and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for changes in cabin temperature by dressing in layers, and pick closed-toe, flat footwear like slip-ons.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To minimize your risk on board, drink lots of water, consider wearing compression socks or tights and keep your legs and feet moving.

How to get through airport security fast when flying to Lake Forest?
Being prepared before you get to the airport will make your getaway to Lake Forest quick and painless. We've compiled some useful tips and tricks for a swift journey past security:

  • Airport security personnel first need to determine that you have a valid passport and travel documents before you're allowed to proceed any further. Have them ready for inspection.
  • After that, both you and your carry-on bag will be X-rayed. To speed things up, remove anything that might set the alarms off. Personal belongings such as your coat, belt and earphones need to go through the machine.
  • All electronic devices, including your phone and tablet, will also need to be scanned separately.
  • Any liquids or gels, such as perfume or toothpaste, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • Lightweight sneakers are a clever footwear choice as you're less likely to have to remove them when going through security. Safety boots and other heavy shoes are usually subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed on board.
