Do you have any tips for my flight to Sisters?
If you're poorly prepared, air travel can be challenging. But there's no need to worry. Follow these tips and tricks for a trouble-free start to your vacation in Sisters. What to pack in your hand luggage:

  • It's simple — first, pack your passport, official ID, bank cards and daily medications. Next, you'll want some entertainment to while away the time. A thrilling book and a laptop crammed with your favourite movies are some great options. If you plan to catch more than just forty winks, a quality neck pillow and some earplugs will also be useful. Finally, leave some space for a toothbrush and some cleansing wipes to ensure you arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hair gel 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 pocket knife, and dangerous goods which are flammable or explosive, such as aerosol cans, flares and matches, are also banned.

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in cabin temperature by wearing layers, and pick flat, slightly roomy shoes like slip-ons.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Reduce the risks by staying hydrated, keeping your legs and feet moving and wearing compression tights or socks.

How to get through airport security fast when flying to Sisters?
Being prepared before you get to the airport will make your trip to Sisters a pleasure. Read through our top tips for a stress-free journey through security:

  • Be sure to keep your passport and boarding pass handy. They're the first things you'll be asked to show at security.
  • The X-ray machine is up next. Remove anything on you that is likely to beep. This includes things 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 gadgets like laptops and phones will also have to go through the machine for inspection. Don't worry though, you'll be back online soon enough.
  • Travelling with your favourite hand and nail cream? No problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you on board.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when passing through security. Big boots and other heavy-style shoes are usually subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked baggage. They won't be allowed on board.
