First up, the essentials: passport, boarding pass, cash and important medications. Next, take on board items that'll help while away those hours, like some electronic gadgets or a thrilling novel. It's also wise to pack your chargers, a neck pillow and a pair of headphones. And of course, be sure to toss in toiletry items like a toothbrush, deodorant and a clean set of clothes. > > > Do not pack the following items in your hand luggage: > > > - Check carefully that you don't have a Swiss Army knife lurking in one of the zippers of your hand luggage. Other restricted items include explosive or flammable products, such as fuel and fireworks, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - The aisles of an aircraft aren't the place for a fashion parade. Layer up with comfortable clothing and opt for shoes that are enclosed, flat and easy to slip on and off. > - You're probably aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To minimize your risk on board, drink lots of water, consider wearing compression tights or socks and move your lower limbs often. ### How to get through airport security fast when flying to Mar del Sur? > - Airport security personnel first need to know that you have a valid passport and matching travel documents before anything else. Have them ready for inspection. > - The X-ray machine is up next. Remove anything metal on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening. > - For just a few moments, you'll have to unplug from the digital world. Your tablet, phone and any other electronic devices also need to be sent through the scanner. > - Travelling with your favourite hand and nail cream? No problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, it's fine to bring with you in your carry-on. > - It's also likely that you'll need to remove your shoes to be X-rayed, so wearing slip-on shoes is always a good idea. > - Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, put them in your checked suitcase. They won't be allowed on board. ## Book with confidence Expedia.ca gives you the best tools to secure great deals on flights to Mar del Sur.
