First things first, you'll need basic toiletries, such as deodorant and a toothbrush, a spare change of clothes and a few magazines. Secondly, find room in your bag for your laptop, a charger, your medications and perhaps a cozy neck pillow as well. Last, but definitely not least, be sure to take 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 a pocket knife lurking in one of the zippers of your carry-on luggage. Other restricted items include explosive or flammable substances, such as aerosol cans and bleach, and gels and liquids in containers larger than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - The aisles of a plane are no place for a fashion parade. Wear layers and opt for shoes that are flat, enclosed and easy to pull on and off. > - The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long-haul flights. Reduce the risks by staying hydrated, keeping your lower limbs moving and wearing compression tights or socks. ### How to get through airport security fast when flying to Warrenville? > - Be sure to keep your boarding pass and ID within easy reach. They're the first things you'll be asked to present to airport security. > - The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening. > - For just a few moments, you'll need to unplug from the digital world. Your tablet, phone and any other electronic devices also need to go through the scanner. > - Travelling with your favourite cologne or perfume? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can bring it with you in your carry-on luggage. > - Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when passing through security. Boots and other heavy-style shoes are usually subjected to additional screening. > - Airlines won't allow any pocket knives or other sharp items in your carry-on baggage. If you need to bring these kinds of items, put them in your checked luggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Warrenville.
