First up, the essentials: passport, boarding pass, cash and important medications. Next, bring on board items that'll help keep you occupied, like some electronic devices or a juicy novel. It's also wise to bring your chargers, a neck pillow and a pair of earplugs. Finally, don't forget to squeeze in toiletry items like a toothbrush, cleansing wipes and a fresh change of clothes. > > > Do not pack the following items in your hand luggage: > > > - Double-check that you don't have a pocket knife hiding in your hand luggage. Other banned items include flammable or explosive products, such as fuel and fireworks, and gels and liquids in containers larger than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Your priority is to be as comfortable as possible. Pick shoes that are easy to slip on and off, dress in loose, breathable clothing and remember to take a jacket in case it gets cold in the cabin. > - Deep vein thrombosis (DVT), a blood clotting condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation. ### How to get through airport security fast when flying to Allenstown? > - Have your travel documents and ID easily accessible. They're the first items you'll be asked for by security. > - Your jacket, belt, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn. > - All electronic gadgets, including your phone and tablet, will also need to be scanned separately. > - Any gels or liquids, such as perfume or hairspray, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag. > - There's a possibility that you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a clever idea. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed on board and will be confiscated. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Allenstown.
