Next, you'll want some entertainment to while away the time. A thrilling book and a laptop filled with your favourite shows are some great options. If you hope to catch up on some sleep, a neck pillow and some earplugs will also come in handy. Finally, leave some space for a toothbrush and some deodorant to ensure you hop off the plane looking fresh and ready to go. > > > Do not pack the following items in your hand luggage: > > > - While the list of restricted items can differ between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes screwdrivers, pocket knives, spray paint and flares. Sporting equipment like hockey sticks, and items that could injure passengers, such as firearms and swords, won't be allowed on board either. > > > What to wear on a flight: > > > - Comfort should be your priority when deciding what to wear during your flight. Loose clothing is a sensible choice, as are flat, slightly roomy shoes. > - Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to improve your circulation. ### How to get through airport security fast when flying to Union? > - Have your boarding pass and passport handy. They'll be the first things you'll be asked to present to airport security. > - The X-ray machine comes next. Remove anything metal on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt. > - Electronic devices like phones and laptops will also have to go through the machine to be scanned. Don't worry though, you'll be back online in no time. > - Travelling with your favourite perfume? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you can keep it with you in your carry-on baggage. > - Lightweight sneakers are a clever footwear choice as you're less likely to be asked to remove them when going through security. Hiking boots and heavier-style shoes are often subjected to additional screening. > - Airlines will not allow any sharp items or pocket knives in your carry-on luggage. If you need to bring these kinds of items, check them in. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Union.
