How to survive the flight to West Riverside?
Wherever you're jetting in from, flying can be an enjoyable experience if you've prepared well enough. Follow these handy hints that will get your West Riverside escape started on the right note.What to pack in your hand luggage:

  • It's easy — first, pack in your passport, important documents, credit cards and daily medications. Next, you'll need some in-flight entertainment to while away the time. A juicy novel and a laptop filled with your favourite movies are some wonderful options. If you intend to take a short snooze, a comfy neck pillow and some noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some deodorant so you'll touchdown looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp objects (like a knife or scissors) hiding in your hand luggage. Other restricted items include flammable or explosive products, such as fuel and fireworks, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The best way to ensure a comfortable flight can be as simple as your choice in clothes. Prepare for changes in temperature by layering up. This will keep you nice and warm if the cabin begins to cool down. Shoes like flip flops and heels are best left in your suitcase. Instead, opt for flat, closed-toed footwear like slip-ons. Your feet will thank you later.
  • Unfortunately, one risk of long flights is developing DVT (deep vein thrombosis), a blood clotting condition caused by extended periods of inactivity. To prevent this from happening, make the most of every opportunity to stretch your legs and walk around the cabin. Compression tights and socks are another great idea to help minimize this risk.

How to get through airport security fast when flying to West Riverside?
It's simple — be prepared. We've compiled some top tips for a speedy trip through security. Watch out West Riverside, here you come:

  • Keep your ID and travel documents easily accessible. They're the first things you'll be asked for by airport security.
  • The X-ray machine comes next. Remove anything on you that is likely to beep. This includes things like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All your electronics, including your laptop and phone, must also be separately scanned.
  • Any liquids or gels, such as hair oil or hand cream, that you want to take on board must be no larger than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • Slip-on shoes are a great footwear choice as you're less likely to be asked to remove them when going through security. Big boots and other heavy-style shoes are often subjected to additional screening.
  • Airlines will not allow any sharp items or pocket knives in your hand luggage. If you need to bring these kinds of items, pack them in your checked baggage.
