How to survive the flight to Belleville?
If you’re poorly prepared, air travel can be daunting. But there’s no need to worry. Follow these handy tips for a worry-free start to your getaway in Belleville.What to pack in your hand luggage:

  • Flying can be a pleasure if you’ve got all the right things. First of all you’ll need toiletry items, such as toothpaste, a toothbrush and some deodorant, a fresh change of clothes and a magazine or two. Next, find room in your carry-on bag for your electronic gadgets, chargers, any vital medications and maybe a cozy neck pillow as well. Last, but definitely not least, be sure to bring your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of banned items can differ between air carriers, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like tools, metal cutlery, fuels and bleaching agents. Sporting equipment like baseball bats, and objects that could injure passengers, such as guns and swords, can’t come on board with you either.

What to wear on a flight:

  • The key to a comfortable flight is often as simple as the clothes you wear. Prepare for changes in temperature by bringing layers. This will keep you nice and warm if the cabin begins to cool down. Shoes like high heels and sandals are best left in your suitcase. Even though they may be your favorites, opt for flat, closed-toed footwear like sneakers. Your feet will appreciate it.
  • A condition called deep vein thrombosis (DVT) is a potential risk on long-haul flights. It’s the result of blood clots forming due to poor circulation. Doing foot and leg exercises while seated helps to prevent this from happening. Wearing a high-quality pair of compression socks or tights is also recommended.

How to get through airport security fast when flying to Belleville?
The secret is to be prepared before you arrive at the security gate. That way, you’ll be boarding that plane to Belleville before you know it. Follow these helpful tips and get your trip off to a spectacular start:

  • Airport security personnel first need to see that you have a valid ID and boarding pass before you can proceed any further. Keep them within easy reach.
  • After that, both you and your carry-on bag will be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Items such as your belt, jacket and headphones need to go through the machine.
  • For just a few moments, you’ll have to unplug from technology. Your phone, tablet and any other electronic devices will also need to be sent through the scanner.
  • Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-close bag.
  • There’s a possibility that you’ll need to take your shoes off for scanning, so wearing lightweight sneakers is always a wise idea.
  • Airlines will not allow any sharp items or pocket knives in your hand luggage. If you must bring these kinds of items, pack them in your checked luggage.
