Do you have any tips for my flight to St. Anthony?
If you're poorly prepared, air travel can be daunting. But don't hit the panic button just yet. Follow these handy hints and enjoy a stress-free start to your getaway in St. Anthony. What to pack in your hand luggage:
  • First things first, pack in your passport, travel documents, bank cards and vital medications. Next, you'll want some in-flight entertainment to while away the hours. A juicy novel and a laptop filled with your favourite movies are good options. If you hope to take a quick nap, a comfy neck pillow and some earplugs will also come in handy. Finally, leave space for a toothbrush and some deodorant to ensure you step off the plane feeling fresh as a daisy.
Do not pack the following items in your hand luggage:
  • Leave all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your precious pocket knife, and dangerous products which are flammable or explosive, such as aerosols and fuels, are also prohibited.
What to wear on a flight:
  • Go for comfort over style. Prepare for changes in cabin temperature by dressing in layers, and pick slightly roomy, flat footwear like slip-ons.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long 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. Anthony?
A little pre-planning before your flight can make your trip to St. Anthony easy and painless. Below you'll find some handy tips and tricks for a speedy journey past security:
  • Your boarding pass and passport will need to be presented to airport security personnel. Keep them handy so you don't hold up the queue.
  • The X-ray machine comes next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • For just a few moments, you'll have to unplug from technology. Your tablet, phone and any other electronic devices will need to be sent through the scanner.
  • Can't travel without your favourite hand and nail cream? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you're permitted to bring it with you in your carry-on.
  • Lightweight sneakers are a practical footwear choice as you're less likely to have to remove them when passing through security. Big boots and heavier-style shoes are usually subjected to additional screening.
  • Airlines will not allow any pocket knives or other sharp items in your hand luggage. If you need to bring these kinds of items, put them in your checked baggage.
