### How long is the flight to Grand Detour Airport? ### How to book the cheapest flight to Grand Detour? ### How to survive the flight to Grand Detour? > - Traveling on a plane can be a cruisy experience if you take the right gear. Firstly, you'll want some toiletry items, such as deodorant, toothpaste and a toothbrush, a spare set of clothes and a good novel. Next, make room in your bag for your electronic gadgets, chargers, your medications and perhaps a quality neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel documents and your bank cards. > > > Do not pack the following items in your hand luggage: > > > - While the list of restricted items can differ between air carriers, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like screwdrivers, blades, spray paint and fireworks. Sporting equipment like hockey sticks, and objects that could injure passengers, such as pepper spray and firearms, won't be allowed on board either. > > > What to wear on a flight: > > > - The long, narrow aisles of a plane are not the best place for a fashion parade. Layer up with comfortable clothing and pack a sweater as it can get quite cool inside the cabin during long-haul flights. Flat, slightly roomy shoes are also a wise idea. > - The serious condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clots forming due to poor circulation. Doing regular leg and foot exercises while seated is a great way to prevent this from occurring. Wearing a pair of compression tights or socks also helps reduce the risk. ### How to get through airport security fast when flying to Grand Detour? > - Security personnel first need to see that you have a valid ID and travel documents before anything else. Have them ready for inspection. > - The X-ray machine comes next. Remove anything metal on you that is likely to beep. This includes items like earphones or headphones, 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. > - Want to bring along your favorite perfume? As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a zip-close bag, you can bring it with you in your carry-on. > - There's a possibility that you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a good idea. > - Sharp items like knives are prohibited in the cabin. They'll be confiscated at security, so pack them safely away in your checked luggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Grand Detour.
