Do you have any tips for my flight to St. Mary?
We've got the lowdown on how to make your flight an enjoyable experience. Follow our tips and you'll be breezing through the airport and having a ball in St. Mary in no time at all. What to pack in your hand luggage:
  • The trick to having an awesome flight experience is to plan ahead. First up, the essentials: passport, boarding pass, bank cards and medications. Next, take on board items that'll help pass the time, like some electronic devices or a few magazines. You'll also want to bring your chargers, a neck pillow and a pair of earplugs. Finally, be sure to chuck in toiletry items like a toothbrush, deodorant and a clean set of clothes.
Do not pack the following items in your hand luggage:
  • While the list of restricted items can differ between air carriers, the general guide to follow is nothing sharp, flammable or explosive. This includes screwdrivers, blades, fuel and fireworks. Sporting equipment like ski poles, and objects that could injure passengers, such as swords and batons, can't come on board with you either.
What to wear on a flight:
  • You'll want to choose comfort over style. Prepare for changes in cabin temperature by layering up, and pick easy-to-remove footwear like sneakers.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clots forming due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.
How to get through airport security fast when flying to St. Mary?
Being prepared before you get to the airport will make your trip to St. Mary a breeze. Below you'll find some useful tips for a stress-free journey through security:
  • Keep your passport and boarding pass someplace easily accessible. They're the first items you'll be asked to present to security.
  • Time to strip down. Well sort of. Your belt, jacket, keys and other small items, like coins, will need to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • All your electronic gadgets, including your laptop and phone, are also required to be scanned.
  • Remove all gels and liquids from your hand luggage. They usually need to be sent through the X-ray scanner separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a great footwear choice as you're less likely to have to remove them when going through security. Boots and other bulky shoes are often subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board.
