Do you have any tips for my flight to Sisters?
No matter where you're coming from, flying can be a seamless experience if you've planned ahead. Take a peek at these handy tips that will get your Sisters escape started on the right note. What to pack in your hand luggage:
  • First and foremost, pack in your passport, travel documents, wallet and daily medications. Next, you'll need some in-flight entertainment to while away the time. A thrilling novel and a tablet filled with your favourite movies are some fantastic options. If you intend to take a quick snooze, a quality neck pillow and a pair of earplugs will also be useful. Finally, find room for a toothbrush and some facial wipes to ensure you touchdown feeling fresh and raring to go.
Do not pack the following items in your hand luggage:
  • Pack all your full-sized bottles of shampoo and hair gel in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like your precious Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosols and strong acids, are also not allowed.
What to wear on a flight:
  • Choose comfort over style. Prepare for changes in cabin temperature by donning layers, and pick easy-to-remove footwear like slip-ons.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lower your risk on board, drink plenty of water, consider wearing compression tights or socks and keep your legs and feet moving.
How to get through airport security fast when flying to Sisters?
Being prepared before you arrive at the airport will help make your getaway to Sisters a piece of cake. We've rounded up some useful tips and tricks for a speedy journey past security:
  • Your ID and travel documents will need to be presented to airport security personnel. Keep them within easy reach to avoid fumbling around for them.
  • After that, both you and your carry-on bag must be X-rayed. To speed things up, take off anything that might trigger the alarms. Personal belongings such as your belt, coat and earphones will be required to go through the machine.
  • For just a few minutes, you'll have to unplug from technology. Your laptop, phone and any other electronics must also go through the scanner.
  • Remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won't be allowed on board.
