How to survive the flight to Union?
We’ve pulled together all the info you need to make your journey as pain-free as possible. Follow our tips and tricks and you’ll be zooming through airport security and seeing the best of Union before you know it.What to pack in your hand luggage:

  • First and foremost, pack in your passport, travel documents, wallet and daily medications. Next, you’ll need some extra in-flight entertainment to help pass the time. A juicy book and a tablet filled with your favourite shows are some wonderful options. If you plan to take a short nap, a neck pillow and a pair of earplugs will also be useful. Finally, make room for a toothbrush and some deodorant to ensure you touchdown looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Double-check that you don’t have a pocket knife lurking in one of the compartments of your hand luggage. Other banned items include flammable or explosive substances, such as aerosol cans and bleach, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The narrow aisles of an airplane are no fashion runway. Layer yourself up with comfortable clothes and pack a cardigan as it can get chilly in the cabin. Slightly roomy, flat shoes are always a good choice too.
  • Unfortunately, a risk of long-distance flying is developing deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity. To prevent this from happening, take every opportunity to wander around the cabin. Compression socks and tights are another easy way to help reduce this risk.

How to get through airport security fast when flying to Union?
Being prepared before you get to the airport can make your getaway to Union a breeze. Here are some top tips for a speedy journey past security:

  • Airport security personnel first need to know that you have a valid ID and matching travel documents before you can proceed any further. Have them in your hand, ready for inspection.
  • Next up, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that might trigger the alarms. Personal belongings like your jacket, belt and headphones will be required to go through the machine.
  • For just a few moments, you’ll need to unplug from the digital world. Your laptop, phone and any other electronic devices also need to go through the scanner.
  • Travelling with your favourite cologne or perfume? Not a problem. As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a clear zip-close bag, it’s OK to bring with you in your carry-on.
  • It’s also likely that you’ll be asked to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a good idea.
  • Airlines won’t allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, pack them safely in your checked luggage.
