Do you have any tips for my flight to Frontenac?
Depending on where you're coming from, your flight to Frontenac could be completely painless or it could go on forever. We've pulled together some useful tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

  • Travelling on a plane can be a great experience if you pack the right gear. Firstly, you'll need basic toiletry items, such as deodorant and a toothbrush, a fresh set of clothes and something to read. Secondly, make room in your carry-on bag for your phone and charger, any daily medications and perhaps a quality neck pillow too. Lastly, remember to take your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between air carriers, the general rule to follow is nothing sharp, flammable or explosive. This includes screwdrivers, blades, aerosol cans and flares. Sporting equipment like ice skates, and items that could injure passengers, such as swords and batons, can't come on board with you either.

What to wear on a flight:

  • Your goal here is to feel as comfortable as you can. Choose flat, closed-toe shoes, dress in loose, breathable clothing and don't forget to bring a sweater in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance 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 Frontenac?
As savvy travellers know, the secret is to be well organised before you arrive at the security gate. That way, you'll be boarding that plane to Frontenac in next to no time. Follow these helpful tips and get your holiday off to a fantastic start:

  • First things first. Your ID and travel documents will need to be presented to security personnel. Keep them handy to avoid fumbling around for them.
  • Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • All your electronic devices, including your laptop and phone, are also required to be separately scanned.
  • Any liquids or gels, such as perfume or toothpaste, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a good footwear choice as you're less likely to have to remove them when going through security. Boots and other heavy shoes are usually subjected to additional screening.
  • Sharp or pointed items are prohibited in the cabin. They'll be seized at security, so pack them in your checked baggage.
