Do you have any tips for my flight to Rantoul?
Wherever you're coming from, flying can be a pleasant experience if you prepare well enough. We've made a list of essential travel tips that will help get your Rantoul escape started on the right foot. What to pack in your hand luggage:

  • Flying can be easy if you take the right stuff. First of all you'll need basic toiletries, such as a toothbrush and hairbrush, a clean set of clothes and a good novel. Next, leave space in your hand luggage for your mobile phone, a charger, medications and perhaps a proper neck pillow as well. Last, but definitely not least, don't forget to bring your passport, travel docs and your credit cards.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects lurking in one of the compartments of your carry-on luggage. Other prohibited 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:

  • Choose comfort over style. Prepare for changes in cabin temperature by wearing layers, and pick closed-toe, flat shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Rantoul?
As seasoned travelers know, the secret is to be prepared before you reach security. That way, you'll be stepping onto that plane to Rantoul in a flash. Follow these helpful tips and get your vacation off to a fantastic start:

  • Have your passport and boarding pass someplace easily accessible. They're the first things you'll be asked to present to airport security.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • Your electronic gadgets like laptops and phones will also have to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Traveling with your favorite cologne or perfume? No problem. As long as the volume is no larger than 3.4 ounces (100 milliliters) and it's stored in a zip-lock bag, you can keep it with you in your carry-on baggage.
  • There's a possibility that you'll be asked to take your shoes off for scanning, so wearing slip-on sneakers is always a clever idea.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board.
