Do you have any tips for my flight to Belleville?
We've got the lowdown on how to make your journey as pain-free as possible. Follow our top tips and you'll be zooming through the airport and discovering Belleville in no time. What to pack in your hand luggage:

  • The trick to having an amazing travel experience is to plan ahead. So, let's start with the essentials: passport, boarding pass, bank cards and any vital medications. Next, bring items that'll help keep you occupied, like some electronic devices or a good read. It's also wise to pack your chargers, a neck pillow and a pair of headphones. Finally, don't forget to squeeze in toiletries like a toothbrush, lip balm and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze 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) will be confiscated. Pointed or sharp objects, like your beloved Swiss Army knife, and dangerous products which are explosive or flammable, such as flares, bleaching agents and matches, are also banned.

What to wear on a flight:

  • Comfort should be your main concern when deciding what to wear on your flight. Loose clothing is a sensible option, as are flat, slightly roomy shoes.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers on long-haul flights. Lower your risks by drinking water, keeping your ankles and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Belleville?
The answer is simple --- be organized. We've compiled some helpful hints for a stress-free trip through airport security. Look out Belleville, here you come:

  • Airport security personnel first need to make sure that you have a valid ID and boarding pass before you're allowed to proceed any further. Have them ready to show.
  • Time to strip down. Well sort of. Your jacket, belt, keys and other small items, like coins, will be required 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 devices, including your phone and tablet, are also required to be scanned.
  • Can't travel without your favourite perfume? As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can bring it with you in your carry-on luggage.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking boots are often required to be removed and separately scanned. Slip-on shoes usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked suitcase. They won't be allowed on board.
