First of all you'll need basic toiletry items, such as a toothbrush and lip balm, a spare change of clothes and a good read. Secondly, find a spot in your carry-on bag for your phone, tablet and chargers, any vital medications and maybe a proper neck pillow too. Last, but definitely not least, be sure to bring your passport, travel documents and some cash. > > > Do not pack the following items in your hand luggage: > > > - While the list of prohibited items can differ between airlines, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, blades, fireworks and fuel. Sports equipment like ice skates, and objects that could harm passengers, such as swords and guns, aren't allowed in the cabin either. > > > What to wear on a flight: > > > - Comfort should be your main concern when choosing what to wear on your flight. Loose clothing is a sensible choice, as are flat, closed-toe shoes. > - Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights. ### How to get through airport security fast when flying to Porthill? > - First things first. Your passport and boarding pass will need to be shown to airport security personnel. Keep them someplace accessible so you don't hold up the queue. > - After that, both you and your carry-on luggage must be X-rayed. To speed things up, take off anything that might set the alarms off. Items such as your belt, coat and headphones need to go through the machine. > - For just a few minutes, you'll have to unplug from the digital world. Your laptop, phone and any other electronic gadgets also need to go through the scanner. > - Any gels or liquids, such as perfume or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag. > - There's a chance you'll need to remove your shoes to be X-rayed, so wearing slip-on shoes is always a smart idea. > - Airlines will not allow any sharp objects in your hand luggage. If you need to bring these kinds of items, put them in your checked luggage. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Porthill.
