How to survive the flight to Illiopolis?
Depending on where you're coming from, your flight to Illiopolis could be completely painless or it could go on forever. Here are some useful travel tips that will help you start your unforgettable escape on the right foot.What to pack in your hand luggage:

  • It's easy — first, put in your passport, travel docs, bank cards and vital medications. Next, you'll need some entertainment to while away the time. A juicy novel and a tablet crammed with your favourite movies are some wonderful options. If you plan to take a quick snooze, a neck pillow and a pair of earplugs will also come in handy. Finally, make room for a toothbrush and some deodorant to ensure you arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a sharp object hiding in your hand luggage. Other banned items include flammable or explosive goods, such as fuel and fireworks, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The key to a comfortable flight can be as simple as your choice of clothes. Prepare for changes in temperature by layering up. That way you'll stay nice and warm if the cabin gets too cold. Shoes like high heels and sandals are best left in your checked suitcase. Even though they may be your favourites, go for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
  • The condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clots forming due to poor circulation and inactivity. Doing leg and foot exercises in your seat is a great way to prevent this happening. Wearing a high-quality pair of compression socks or tights is also a wise idea.

How to get through airport security fast when flying to Illiopolis?
The answer is simple — be prepared. We've pulled together some helpful hints for a stress-free trip through airport security. Watch out Illiopolis, here you come:

  • Keep your passport and boarding pass within close reach. They're the first items you'll be asked to show at security.
  • Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Electronic devices like phones and laptops will also need to go on a tray to be scanned. No need to worry though, you'll be back online before you know it.
  • Travelling with a new perfume? As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, it's OK to bring with you in your carry-on.
  • The right choice of footwear can save you several valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Knives and other sharp items are not allowed in the cabin. They'll be confiscated at security, so put them in your checked bags.
