How to survive the flight to Union?
If you’re not prepared, travelling can be daunting. But there’s no need to panic. Follow these handy hints and enjoy a pleasant start to your holiday in Union.What to pack in your hand luggage:

  • Air travel can be a pleasure if you take the right gear. Firstly, you’ll need basic toiletries, such as deodorant and a toothbrush, a clean pair of socks and a magazine or two. Next, find room in your hand luggage for your laptop, a charger, any daily medications and maybe a proper neck pillow too. Last, but definitely not least, don’t forget to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like knives, scissors, aerosol cans and bleaching agents. Sports equipment like ski poles, and objects that could harm passengers, such as pepper spray and firearms, can’t come on board with you either.

What to wear on a flight:

  • The narrow aisles of your plane are no fashion runway. Wear comfortable clothes and take a sweater as it tends to get cool inside the cabin. Slightly roomy, flat shoes are also a sensible choice.
  • A condition called deep vein thrombosis (DVT) is a potential risk on long-haul flights. It results from blood clots forming due to poor circulation. Doing regular leg and foot exercises in your seat helps to prevent this developing. Wearing a good-quality pair of compression socks or tights also helps reduce your risk.

How to get through airport security fast when flying to Union?
The secret is to be well prepared before you reach airport security. That way, you’ll be hopping onto that plane to Union in no time at all. Follow these helpful tips and get your holiday off to a great start:

  • Airport security personnel first need to make sure that you have a valid passport and matching travel documents before you’re allowed to proceed any further. Have them ready to show.
  • The X-ray machine is up next. Empty your pockets and remove anything that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They’ll all need to go on the X-ray conveyor belt.
  • All your electronics, including your phone and laptop, are also required to be scanned separately.
  • Any gels or liquids, such as shampoo or hand cream, that you want to take on board need to be in containers no greater than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked suitcase. They won’t be allowed on board.
