Firstly, you'll want a few toiletry items, such as a toothbrush and lip balm, a spare set of clothes and a few magazines. Secondly, leave space in your hand luggage for your mobile phone, a charger, your important medications and maybe a blow-up neck pillow too. Lastly, don't forget to bring your passport, travel papers and your credit cards. > > > Do not pack the following items in your hand luggage: > > > - Leave all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp or pointed objects, like your beloved pocket knife, and dangerous goods which are explosive or flammable, such as aerosol cans, flares and gasoline, are also not allowed. > > > What to wear on a flight: > > > - Go for comfort over style. Prepare for changes in cabin temperature by layering up, and opt for flat, enclosed footwear like sneakers. > - Deep vein thrombosis (DVT) can pose a risk on long-distance 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 tights or socks. ### How to get through airport security fast when flying to Ottawa? > - Security personnel first need to see that you have a valid passport and travel documents before you can proceed any further. Have them ready to show. > - After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Items such as your coat, belt and headphones need to go through the machine. > - All your electronic devices, including your phone and laptop, will also need to be separately scanned. > - Travelling with a new perfume? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you're permitted to bring it with you on board. > - There's a good chance you'll be asked to take your shoes off for scanning, so wearing slip-on sneakers is always a smart 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 baggage. They won't be allowed on board and will be confiscated. ## Book with confidence # Expedia flights to Ottawa Searching for cheap flights to Ottawa?
