Finally, be sure to toss in toiletries like a toothbrush, lip balm and a fresh set of clothes. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items can differ between airlines, the general rule to follow is nothing flammable, sharp or explosive. This includes screwdrivers, knives, spray paint and fireworks. Sports equipment like baseball bats, and items that could injure passengers, such as guns and swords, are also banned from the cabin. > > > What to wear on a flight: > > > - You'll want to choose comfort over style. Prepare for temperature changes by dressing in layers, and pick slightly roomy, flat shoes like sneakers. > - The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long 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 Prairie du Rocher? > - Keep your boarding pass and ID easily accessible. They'll be the first things you'll be asked to present to security. > - After that, both you and your hand luggage must be X-rayed.

Don't worry, you'll be back online soon enough. > - Can't travel without your favourite perfume or cologne? 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 on board. > - There's a possibility that you'll need to take your shoes off for scanning, so wearing lightweight sneakers is always a smart idea. > - Airlines will not allow any pocket knives or other sharp items in your carry-on luggage.
