Do you have any tips for my flight to Belleville?
Wherever you're jetting in from, flying can be a pleasurable experience if you've planned ahead. Follow these handy hints that will get your Belleville vacation started on the right note. What to pack in your hand luggage:

  • Travelling on a plane can be a comfortable experience if you take the right stuff. Firstly, you'll need basic toiletries, such as a toothbrush and some deodorant, a spare change of clothes and a good book. Next, find a spot in your carry-on bag for your phone and charger, your medications and maybe a quality neck pillow too. Lastly, and most importantly, remember to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hairspray in your checked luggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your beloved Swiss Army knife, and dangerous goods which are explosive or flammable, such as aerosol cans, flares and poisons, are also restricted.

What to wear on a flight:

  • You'll want to go for comfort over style. Prepare for changes in cabin temperature by dressing in layers, and opt for easy-to-remove shoes like sneakers.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. Reduce the risks by staying hydrated, keeping your legs moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Belleville?
The secret is to be prepared before you reach the airport security gate. That way, you'll be stepping onto that plane to Belleville in no time at all. Follow these tips and get your vacation off to a great start:

  • Your travel ID and boarding pass will need to be shown to security personnel. Keep them at hand to avoid fumbling around for them.
  • Next up is the X-ray machine. Empty your pockets and remove anything that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like phones and laptops will also have to go through the machine for inspection. Don't worry, you'll be back online in no time.
  • Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • There's a good chance you'll be asked to remove your shoes for scanning, so wearing lightweight sneakers is always a clever idea.
  • Sharp items like knives can't be taken on board. They'll be seized at security, so put them in your checked baggage.
