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

  • First and foremost, pack your passport, travel documents, cash and daily medications. Next, you'll need some extra in-flight entertainment to while away the time. A thrilling book and a tablet filled with your favourite shows are some great options. If you intend to catch more than just forty winks, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, squeeze in a few toiletry items so you'll arrive feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes box cutters, razor blades, fireworks and fuel. Sporting equipment like golf clubs, and objects that could harm other people, such as pepper spray and guns, can't come on board with you either.

What to wear on a flight:

  • The aisles of a plane aren't the place for a fashion parade. Dress in comfortable layers and pick shoes that are flat and easy to pull on and off.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from 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 Cascade?
Being organized before your flight will make your trip to Cascade easy and painless. Check out our useful tips for a swift journey through security:

  • Your travel ID and boarding pass will need to be inspected by security personnel. Keep them someplace accessible so you don't hold up the queue.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • All your electronic devices, including your tablet and phone, will also need to be scanned.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a good footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other heavy shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed on board and will be confiscated.
