Do you have any tips for my flight to St. Clair?
Wherever you're coming from, flying can be a seamless experience if you've prepared well. We've compiled a list of handy travel tips that will help get your St. Clair escape started on the right note. What to pack in your hand luggage:

  • Travelling on a plane can be easy if you take the right stuff. Firstly, you'll want a few toiletry items, such as deodorant, toothpaste and a toothbrush, a clean pair of socks and a good novel. Next, leave space in your bag for your mobile phone, a charger, any daily medications and perhaps a blow-up neck pillow as well. Lastly, remember to bring your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • Make sure you don't have sharp or pointed objects hiding in the bottom of your carry-on luggage. Other prohibited items include flammable or explosive goods, such as fuel and matches, and gels and liquids in containers larger than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • The aisles of a plane are no place for a fashion parade. Dress in comfortable layers and choose shoes that are roomy, flat and easy to take on and off.
  • You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To minimize your risk on board, drink plenty of water, consider wearing compression tights or socks and move your lower limbs often.

How to get through airport security fast when flying to St. Clair?
Being organised before your flight will make your trip to St. Clair a piece of cake. Below are some handy hints for a speedy journey through security:

  • First things first. Your boarding pass and travel ID will need to be shown to security personnel. Have them easily accessible to avoid fumbling around for them.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to beep. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online before you know it.
  • Any gels or liquids, such as perfume or hairspray, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and heavier-style shoes are usually subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed on board and will be confiscated.
