Firstly, you'll want some toiletry items, such as a toothbrush and hairbrush, a clean set of clothes and something to read. Secondly, find room in your hand luggage for your electronic devices, chargers, your medications and perhaps a neck pillow as well. Lastly, don't forget to bring your passport, travel documents and some money. > > > Do not pack the following items in your hand luggage: > > > - Pack all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your treasured pocket knife, and products which are explosive or flammable, such as spray paint, flares and poisons, are also not allowed. > > > What to wear on a flight: > > > - The aisles of an airplane aren't the place for a fashion parade. Don comfortable layers and go for shoes that are enclosed, flat and easy to slip on and off. > - Caused by lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-haul flights. Lower your risks by drinking water, 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 Saint Mary's City? > - Airport security personnel first need to make sure that you have a valid ID and travel documents before anything else. Have them within easy reach, ready for inspection. > - The X-ray machine is up next. Empty your pockets and remove anything that is likely to set off the alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt. > - All your electronic devices, including your phone and tablet, are also required to be scanned. > - Want to bring along your favourite cologne or perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's fine to bring with you in your carry-on bag. > - There's a good chance you'll be required to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a smart idea. > - Airlines won't allow any sharp items or pocket knives in your carry-on luggage. If you must bring these kinds of items, pack them in your checked luggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Saint Mary's City.
