Do you have any tips for my flight to St. Mary's?
No matter where you're coming from, flying can be a seamless experience if you've prepared well. Follow these essential travel tips that will get your St. Mary's vacation started on the right foot. What to pack in your hand luggage:
  • The secret to having a stress-free flight experience is to plan ahead. Start with the essentials: passport, boarding pass, bank cards and daily medications. Next, bring items that'll help keep you occupied, like some electronic gadgets or a good book. It's also a wise idea to pack your chargers, a quality neck pillow and a pair of earphones. Last but not least, don't forget to squeeze in toiletry items like a toothbrush, cleansing wipes and a clean set of clothes.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have sharp or pointed objects lurking in the bottom of your carry-on luggage. Other banned items include flammable or explosive substances, such as fuel and fireworks, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your goal here is to be as comfortable as you can. Go for shoes that are easy to slip on and off, dress in loose, natural fibers and don't forget to take a pullover in case you get chilly in the cabin.
  • Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clots forming due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.
How to get through airport security fast when flying to St. Mary's?
It's all about being organized. We've compiled some top tips for a speedy trip through airport security. Look out St. Mary's, here you come:
  • Your passport and travel documents will need to be shown to security personnel. Keep them at hand to avoid fumbling around for them.
  • Time to strip down. Well sort of. Your coat, belt, keys and other small items, like your earphones, will need to go through the X-ray machine. Make the whole process easier by removing them as it gets closer to your turn.
  • Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. Don't worry though, you'll be back online in no time.
  • Any liquids or gels, such as perfume or toothpaste, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several precious minutes. Hiking or heavy-style boots are often required to be removed and separately scanned. Slip-on shoes are usually not.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked suitcase. They won't be allowed in the cabin.
