Do you have any tips for my flight to Grayslake?
Wherever you're coming from, flying can be a seamless experience if you're prepared. We've put together a list of top travel tips that will get your Grayslake escape started on the right foot. What to pack in your hand luggage:

  • First of all, pack in your passport, important documents, credit cards and daily medications. Next, you'll want some entertainment to while away the hours. A thrilling novel and a laptop filled with your favourite shows are some great options. If you plan to catch more than just forty winks, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, leave space for a toothbrush and some deodorant to ensure you arrive feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like your beloved Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and poisons, are also restricted.

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in temperature by wearing layers, and pick closed-toe, flat shoes like slip-ons.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Lower your risks by staying hydrated, keeping your legs and feet moving and wearing compression tights or socks.

How to get through airport security fast when flying to Grayslake?
As seasoned travellers know, the secret is to be prepared before you get to security. That way, you'll be hopping onto that plane to Grayslake in no time at all. Follow these tips and get your trip off to a great start:

  • Be sure to keep your ID and travel documents handy. They're the first items you'll be asked for by airport security.
  • Your belt, coat, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • All your electronic devices, including your laptop and phone, are also required to be scanned.
  • Remember to remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • It's also possible you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a good idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked suitcase. They won't be allowed on board and will be confiscated.
