Do you have any tips for my flight to St. Marys?
Depending on where you're coming from, your flight to St. Marys could be no sweat at all or it could drag on forever. We've rounded up some tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:
  • It's simple — first, pack your passport, travel documents, wallet and medications. Next, you'll want some entertainment to while away the time. A thrilling novel and a laptop filled with your favourite movies are good options. If you intend to take a quick nap, a comfy neck pillow and some noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some facial wipes so you'll arrive looking and feeling fresh.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have a sharp object hiding in the bottom of your carry-on luggage. Other restricted items include flammable or explosive products, such as fuel and matches, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Comfort should be your number one priority when deciding what to wear during your flight. Loose, breathable clothing is a wise choice, as are flat, enclosed shoes.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Lower your risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks or tights.
How to get through airport security fast when flying to St. Marys?
Being organised before you get to the airport will help make your trip to St. Marys quick and painless. Here are some handy hints for a stress-free journey through security:
  • Be sure to have your ID and boarding pass easily accessible. They'll be the first things you'll be asked to show at security.
  • The X-ray machine comes next. Remove anything on you that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • For just a few minutes, you'll need to unplug from technology. Your tablet, phone and any other electronic gadgets will need to go through the scanner.
  • Remove all liquids and gels from your hand luggage. They often need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several valuable minutes. Boots are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
  • Airlines won't allow any sharp objects in your hand luggage. If you must bring these kinds of items, check them in.
