Firstly, you'll want a few toiletry items, such as a toothbrush and some deodorant, a fresh set of clothes and a magazine or two. Next, make room in your carry-on bag for your phone and charger, your medications and perhaps a neck pillow as well. Lastly, remember to take your passport, travel papers and your bank cards. > > > Do not pack the following items in your hand luggage: > > > - Make sure you don't have sharp objects (like a pocket knife) lurking in the bottom of your carry-on luggage. Other banned items include explosive or flammable substances, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Your goal here is to feel as comfortable as you can. Go for a pair of flat, closed-toe shoes, dress in loose, natural fibers and don't forget to bring a jacket in case you get chilly in the cabin. > - Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To minimize your risk on board, drink lots of water, consider wearing compression tights or socks and keep your feet and legs moving. ### How to get through airport security fast when flying to Waterloo? > - First things first. Your travel documents and passport will need to be inspected by security personnel. Keep them at hand so you don't hold up the queue. > - Next up, both you and your carry-on luggage will be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Personal belongings such as your coat, belt and headphones need to go through the machine. > - All electronic devices, including your tablet and phone, are also required to be scanned separately. > - Any liquids or gels, such as shampoo or hand cream, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag. > - It's also likely that you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a wise idea. > - Sharp or pointed items are not allowed in the cabin. They'll be seized at security, so pack them in your checked baggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Waterloo.
