Do you have any tips for my flight to Warrenville?
Depending on where you're coming from, your flight to Warrenville could be completely stress-free or it could drag on forever. We've compiled some handy travel tips that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

  • A plane trip can be a great experience if you bring the right stuff. Firstly, you'll need basic toiletries, such as lip balm and hand cream, a spare change of clothes and a good read. Next, make room in your bag for your electronic gadgets, chargers, medications and perhaps a proper neck pillow as well. Lastly, and most importantly, remember to take your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between air carriers, the general guide to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, drills, spray paint and flares. Sporting equipment like baseball bats, and items that could injure passengers, such as guns and swords, can't come on board with you either.

What to wear on a flight:

  • Comfort should be your highest priority when deciding what to wear on your flight. Loose, breathable clothing is a sensible choice, as are roomy, closed-toe shoes.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It's the result of blood clotting due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Warrenville?
A little pre-planning before your flight will help make your trip to Warrenville a piece of cake. Read through our handy hints for a swift journey through security:

  • Airport security personnel first need to establish that you have a valid passport and matching travel documents before anything else. Have them ready for inspection.
  • Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • All your electronic devices, including your phone and tablet, are also required to be scanned.
  • Remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when going through security. Big boots and other bulky shoes are usually subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed on board.
