How to survive the flight to St. Clair?
We’ve got the lowdown on how to make your flight a stress-free experience. Follow our tips and tricks and you’ll be speeding through airport security and discovering St. Clair before you know it.What to pack in your hand luggage:

  • Air travel can be a great experience if you bring the right things. First of all you’ll need basic toiletries, such as toothpaste, a toothbrush and some deodorant, a clean set of clothes and a good book. Next, find a spot in your carry-on bag for your phone, tablet and chargers, your important medications and maybe a blow-up neck pillow as well. Lastly, don’t forget to take your passport, travel documents and some cash.

Do not pack the following items in your hand luggage:

  • While the list of restricted items differs between airlines, the general rule to follow is nothing sharp, flammable or explosive. This includes box cutters, razor blades, aerosol cans and flares. Sporting equipment like ice skates, and items that could injure passengers, such as firearms and swords, won’t be allowed on board either.

What to wear on a flight:

  • Comfort should be your prime concern when choosing what to wear on your flight. Consider your footwear with care too, as swollen feet and ankles can be a side effect of flying. Flat, slightly roomy shoes are your best bet.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. There are plenty of ways to reduce your risk. Wear a quality pair of compression tights or socks, stay hydrated and keep your legs and feet moving. Walk the aisles of the cabin or try out some simple stretches in your seat.

How to get through airport security fast when flying to St. Clair?
The simple answer is — be prepared. We’ve rounded up some handy tips and tricks for a fuss-free trip through airport security. Watch out St. Clair, here you come:

  • Airport security personnel first need to see that you have a valid ID and boarding pass before you’re allowed to proceed any further. Keep them within easy reach.
  • Time to strip down. Well kind of. Your belt, jacket, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
  • For just a few moments, you’ll have to unplug from technology. Your laptop, phone and any other electronics will need to go through the scanner.
  • Don’t forget to remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a great 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 often subjected to additional screening.
  • Airlines won’t allow any sharp objects in the cabin. If you must bring these kinds of items, pack them safely in your checked baggage.
