How to survive the flight to Union?
If you’re not prepared, air travel can be a real challenge. But there’s no need to hit the panic button just yet. Follow these handy tips and enjoy a worry-free start to your holiday in Union.What to pack in your hand luggage:

  • A plane ride can be easy if you carry the right things. First things first, you’ll need basic toiletry items, such as a toothbrush and hairbrush, a spare pair of socks and a good book. Next, make room in your carry-on bag for your mobile phone, a charger, your important medications and maybe a cosy neck pillow as well. Last, but definitely not least, be sure to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • Make sure you don’t have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other prohibited items include flammable or explosive products, such as fuel and fireworks, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • Your number one priority is to be as comfortable as possible. Layer up with loose, breathable clothing and don’t forget to pack a pullover just in case you get chilly. Always opt for well-fitting, flat shoes as it’s possible that your feet and ankles will swell during the journey. Leave the high heels and chunky boots in your checked baggage.
  • Unfortunately, a risk of flying long-haul is developing deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To avoid this, take every opportunity to stretch your legs and walk around the cabin. Compression socks and tights are another great idea to help minimize this risk.

How to get through airport security fast when flying to Union?
It’s easy — be prepared. We’ve compiled some tips and tricks for a stress-free trip through airport security. Look out Union, here you come:

  • Airport security personnel first need to see that you have a valid passport and matching boarding pass before you’re allowed to proceed any further. Keep them close by.
  • Time to strip down. Well sort of. Your coat, belt, keys and other contents of your pockets, like your headphones, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn.
  • All your electronic devices, including your phone and tablet, are also required to be scanned separately.
  • Remember to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a practical footwear choice as you’re less likely to be asked to remove them when passing through security. Big boots and other heavy-style shoes are often subjected to additional screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked baggage. They won’t be allowed on board and will be confiscated.
