> - The secret to having an amazing flight experience is to pack in advance. So, let's start with the basics: passport, boarding pass, bank cards and any vital medications. Next, bring on board items that'll help while away those hours, like some electronic gadgets or a good book. You'll also want to pack your chargers, a neck pillow and a pair of noise-canceling headphones. Last but not least, be sure to chuck in toiletries like a toothbrush, facial wipes and a spare change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Make sure you don't have a pocket knife hiding in your hand luggage. Other prohibited items include flammable or explosive substances, such as fuel and fireworks, and liquids and gels in containers with a volume of more than 3.4 ounces (100 milliliters). > > > What to wear on a flight: > > > - The long, narrow aisles of your plane are not the best place for a fashion parade. Don comfortable layers and don't forget to bring a cardigan as it can get chilly in the cabin on long-haul flights. Enclosed, flat shoes are also a good choice. > - Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a serious condition that can affect some passengers on long-distance flights. But the good news is there are ways to reduce the risk of developing it. Stay well hydrated, get up and walk around the cabin as much as you can and wear compression tights or socks. ### How to get through airport security fast when flying to Assumption? > - First things first. Your boarding pass and travel ID will need to be inspected by security personnel. Keep them handy so you don't hold up the queue. > - Next up is the X-ray machine. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt. > - All electronic devices, including your tablet and phone, will also need to be separately scanned. > - Remember to remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-lock bag. > - There's a good chance you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a good idea. > - Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you need to bring these kinds of items, pack them in your checked luggage. \*Flight schedules are subject to change. ## Book with confidence # Tips to find the cheapest flights to Assumption **The cheapest day to fly** Get started finding a cheap flight to Assumption on Expedia by either choosing a deal on this page or entering into the search bar your travel dates, origin airport, and whether you want roundtrip or one-way airfare.
