Do you have any tips for my flight to Union?
No matter where you're coming from, flying can be a pleasant experience if you've planned ahead. We've made a list of handy tips and tricks that will help get your Union holiday started on the right note. What to pack in your hand luggage:
  • The trick to having a worry-free flight experience is to pack ahead. First up, the essentials: passport, travel documents, credit cards and important medications. Next, take on board items that'll help pass the time, like some electronic gadgets or a juicy novel. It's also smart to bring your chargers, a quality neck pillow and a pair of earplugs. And of course, don't forget to chuck in toiletries like a toothbrush, cleansing wipes and a spare set of clothes.
Do not pack the following items in your hand luggage:
  • Double-check that you don't have a Swiss Army knife hiding in one of the compartments of your hand luggage. Other restricted items include explosive or flammable substances, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your main aim is to feel as comfortable as you can. Go for easy-to-remove footwear, dress in loose, breathable clothing and don't forget to bring a sweater in case it gets chilly in the cabin.
  • Deep vein thrombosis (DVT) is a risk on long-distance flights. It results from blood clots forming due to poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.
How to get through airport security fast when flying to Union?
The secret is to be organised before you reach the security gate. That way, you'll be hopping onto that plane to Union in no time flat. Follow these tips and get your holiday off to a fantastic start:
  • Keep your passport and travel documents at hand. They're the first items you'll be asked to show at airport security.
  • The X-ray machine is up next. Remove anything on you that is likely to beep. This includes items like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • Electronic devices like phones and laptops will also need to go on a tray for inspection. No need to worry though, you'll be back online soon enough.
  • Any liquids or gels, such as lip balm or cologne, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a sensible footwear choice as you're less likely to be asked to remove them when going through security. 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 objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed in the cabin.
