Do you have any tips for my flight to Illiopolis?
We've pulled together all the info you need to make your flight an enjoyable experience. Follow our tips and you'll be cruising through the airport and enjoying Illiopolis in no time. What to pack in your hand luggage:

  • The secret to having a hassle-free travel experience is to pack ahead. First up, the essentials: passport, travel docs, cash and medications. Next, take on board items that'll help keep you busy, like some electronic gadgets or a thrilling book. It's also wise to pack your chargers, a neck pillow and a pair of noise-canceling headphones. Finally, don't forget to pop in toiletries like a toothbrush, facial wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by authorities. Sharp or pointed objects, like your treasured pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, flares and poisons, are also banned.

What to wear on a flight:

  • Your priority is to be as comfortable as you can. Opt for easy-to-remove footwear, dress in loose, natural fibers and don't forget to take a sweater in case it gets chilly in the cabin.
  • Most travelers are aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lessen your risk on board, drink plenty of water, consider wearing compression socks and move your lower limbs often.

How to get through airport security fast when flying to Illiopolis?
The answer is simple — be organized. We've compiled some helpful hints for a hassle-free trip through airport security. Look out Illiopolis, here you come:

  • Your travel documents and passport will need to be presented to security personnel. Have them easily accessible so you don't have to dig around for them.
  • The X-ray machine comes next. Remove anything metal on you that is likely to beep. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • All your electronic devices, including your laptop and phone, will also need to be separately scanned.
  • Don't forget to remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray scanner separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-close bag.
  • There's a possibility that you'll need to take your shoes off for scanning, so wearing lightweight sneakers is always a wise idea.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed on board.
