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

  • Travelling on a plane can be a pleasure if you carry the right stuff. First of all you'll need toiletry items, such as deodorant and a toothbrush, a clean pair of socks and a good read. Secondly, find room in your hand luggage for your electronic devices, chargers, any vital medications and perhaps a cozy neck pillow too. Lastly, don't forget to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes knives, scissors, fuels and bleaching agents. Sports equipment like hockey sticks, and objects that could injure passengers, such as guns and swords, are also banned from the cabin.

What to wear on a flight:

  • Choose comfort over style. Prepare for changes in temperature by layering up, and wear flat, easy-to-remove footwear like slip-ons.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Collinsville?
The answer is — be prepared. We've put together some tips and tricks for a speedy trip through security. Watch out Collinsville, here you come:

  • Airport security personnel first need to check that you have a valid passport and travel documents before anything else. Have them in your hand, ready for inspection.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll have to unplug from the digital world. Your tablet, phone and any other electronic devices will need to go through the scanner.
  • Want to bring along your favourite perfume? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can bring it with you in your carry-on luggage.
  • There's a good chance you'll need to take your shoes off to be X-rayed, 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, pack them in your checked baggage. They won't be allowed in the cabin.
