First things first, you'll need toiletry items, such as deodorant and a toothbrush, a clean set of clothes and a few magazines. Next, find a spot in your carry-on bag for your phone and charger, any daily medications and perhaps a blow-up neck pillow as well. Lastly, don't forget to take your passport, travel documents and your bank cards. > > > Do not pack the following items in your hand luggage: > > > - Double-check that you don't have sharp objects (like a knife or scissors) hiding in one of the zippers of your hand luggage. Other banned items include explosive or flammable products, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres). > > > What to wear on a flight: > > > - Comfort should be your main concern when choosing what to wear on your flight. Loose, breathable clothing is a sensible option, as are flat, closed-toe shoes. > - Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers on long-distance flights. Lower your risks by staying hydrated, keeping your legs and feet moving and wearing compression socks to help your circulation. ### How to get through airport security fast when flying to Ontario? > - First things first. Your boarding pass and passport will need to be inspected by airport security. Have them close by so you don't have to dig around for them. > - The X-ray machine comes next. Remove anything on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt. > - Your electronic devices like laptops and phones will also have to go on a tray to be scanned. Don't worry, you'll be back online before you know it. > - Any gels or liquids, such as lip balm or cologne, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag. > - The right choice of footwear can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on sneakers are usually not. > - Sharp items such as knives and scissors are not allowed in the cabin. They'll be confiscated at security, so pack them safely away in your checked luggage. __Flights to Ontario information__ | Destination airport | Boise | | ----------------------------- | ------- | | Destination airport IATA code | BOI | | Destination city name | Boise | | Roundtrip price | CA $185 | ## Trending flights to Ontario Prices were available within the past 7 days and start at CA $80 for one-way flights and CA $185 for round trip, for the period specified.
