Do you have any tips for my flight to St. Ann?
If you're poorly prepared, airports and flying can be testing. But don't hit the panic button just yet. Follow these tips and tricks and enjoy a hassle-free start to your vacation in St. Ann. What to pack in your hand luggage:
  • Travelling on a plane can be a comfortable experience if you carry the right stuff. First things first, you'll need basic toiletry items, such as a toothbrush and some deodorant, a fresh change of clothes and a few magazines. Next, leave space in your bag for your phone and charger, your important medications and perhaps a neck pillow as well. Lastly, be sure to bring your passport, travel docs and your credit cards.
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 avoid carrying anything sharp, flammable or explosive. This includes things like box cutters, razor blades, fuels and bleaching agents. Sports equipment like hockey sticks, and items that could harm passengers, such as swords and batons, won't be allowed on board either.
What to wear on a flight:
  • Your top priority is to feel as comfortable as possible. Choose shoes that are easy to pull on and off, dress in loose, breathable clothing and remember to bring a jacket in case it gets chilly in the cabin.
  • The result of sustained periods of immobility, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Reduce the risks by drinking water, keeping your feet and legs moving and wearing compression socks to help improve your circulation.
How to get through airport security fast when flying to St. Ann?
As savvy travellers know, the secret is to be well prepared before you reach the airport security gate. That way, you'll be hopping onto that plane to St. Ann in next to no time. Follow these tips and get your vacation off to a flying start:
  • Have your travel documents and ID within easy reach. They're the first things you'll be asked for by airport security.
  • Your coat, belt, keys and other small items, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • All your electronics, including your tablet and phone, are also required to be separately scanned.
  • Travelling with your favourite cologne or perfume? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, it's fine to bring with you in your carry-on bag.
  • The right choice of footwear can save you a few precious minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
  • Airlines will not allow any sharp or pointed objects in the cabin. If you need to bring these kinds of items, put them in your checked baggage.
