Frequently asked questions

How to book the cheapest flight to St. Marys?
If you want to save some cash on your trip to St. Marys, then listen up! As every experienced traveller knows, avoid booking at the last minute. Prices are usually more expensive close to the departure date. Another great way to nab the best price is to shop around. If your destination has a few airports, don't forget to research the cost of flying into a less busy terminal. Last but not least, be ready to lock in your seat quickly if you find a real bargain. It might not be available for too long! With a bit of knowledge and some luck, the perfect fare can be yours.
Do you have any tips for my flight to St. Marys?
We've got the lowdown on how to make your flight as enjoyable as possible. Follow our tips and you'll be zooming through airport security and enjoying St. Marys before you know it. What to pack in your hand luggage:

  • Flying can be easy if you pack the right things. Firstly, you'll want some toiletry items, such as deodorant and a toothbrush, a fresh set of clothes and a few magazines. Secondly, find a spot in your hand luggage for your electronic devices, chargers, medications and perhaps a blow-up neck pillow too. Lastly, and most importantly, be sure to take your passport, travel docs and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general guide to follow is nothing flammable, sharp or explosive. This includes things like tools, metal cutlery, fuel and fireworks. Sporting equipment like baseball bats, and items that could harm passengers, such as firearms and ammunition, are also banned from the cabin.

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes in the cabin by layering up, and pick flat, enclosed footwear like slip-ons.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clots forming due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks or tights.

How to get through airport security fast when flying to St. Marys?
A little pre-planning before you get to the airport will help make your getaway to St. Marys easy and painless. Below you'll find some useful tips and tricks for a speedy journey through security:

  • Security personnel first need to make sure that you have a valid passport and matching travel documents before you can proceed any further. Have them within easy reach, ready for inspection.
  • Your coat, belt, keys and other items in your pocket, like your headphones, will be required to go through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • All electronic gadgets, including your phone and laptop, are also required to be separately scanned.
  • Remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray 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-lock bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
  • Airlines won't allow any sharp items or pocket knives in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked luggage.
