How to survive the flight to Saint Constant?
No matter where you’re coming from, flying can be a pleasant experience if you prepare well enough. Follow these essential travel tips that will help get your Saint Constant holiday started on the right foot.What to pack in your hand luggage:

  • The secret to having a great travel experience is to be prepared. First up, the essentials: passport, official ID, credit cards and any vital medications. Next, bring items that’ll help keep you entertained, like some electronic gadgets or a good book. It’s also smart to pack your chargers, a quality neck pillow and a pair of headphones. Finally, don’t forget to squeeze in toiletries like a toothbrush, cleansing wipes and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of banned items differs between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes screwdrivers, knives, spray paint and flares. Sporting equipment like hockey sticks, and items that could harm other people, such as firearms and swords, can’t come on board with you either.

What to wear on a flight:

  • The best way to ensure a comfortable flight can be as simple as your choice in clothes. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin gets too cold. Shoes like high heels and sandals are best left for other occasions. Even though they may be your favourites, go for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
  • A condition called deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clotting due to poor circulation. Doing regular foot and leg exercises while seated helps to prevent this happening. Wearing a high-quality pair of compression socks or tights also helps reduce the risk.

How to get through airport security fast when flying to Saint Constant?
It’s all about being prepared. We’ve pulled together some helpful hints for a fuss-free trip through security. Watch out Saint Constant, here you come:

  • First things first. Your passport and boarding pass will need to be presented to airport security personnel. Keep them someplace accessible so you don’t hold up the line.
  • After that, both you and your carry-on luggage must be X-rayed. To speed things up, take off anything that might trigger the alarms. Personal belongings such as your belt, coat and headphones will be required to go through the machine.
  • Your electronic gadgets like phones and laptops will also have to go through the machine to be scanned. Don’t worry though, you’ll be back online in no time.
  • Any gels or liquids, such as perfume or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). They must also all fit inside a quart-size (one litre), zip-lock bag.
  • Slip-on shoes are a great footwear choice as you’re less likely to have to remove them when passing through security. Safety boots and heavier-style shoes are often subjected to extra screening.
  • Sharp items like knives are prohibited in the cabin. They’ll be seized at security, so put them in your checked baggage.
