Do you have any tips for my flight to Union?
Wherever you're jetting in from, flying can be a pleasurable experience if you prepare well enough. Check out these handy hints that will get your Union holiday started on the right note. What to pack in your hand luggage:
  • The trick to having a worry-free travel experience is to pack in advance. Start with the essentials: passport, travel documents, bank cards and important medications. Next, take on board items that'll help keep you entertained, like some electronic gadgets or a magazine. It's also smart to pack your chargers, a comfy neck pillow and a pair of earplugs. Finally, be sure to chuck in toiletry items like a toothbrush, facial wipes and a spare set of clothes.
Do not pack the following items in your hand luggage:
  • While the list of restricted items differs between airlines, the general rule of thumb is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, drills, fuels and bleaching agents. Sports equipment like baseball bats, and objects that could harm other people, such as pepper spray and firearms, are also banned from the cabin.
What to wear on a flight:
  • Your goal here is to feel as comfortable as possible. Opt for shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and remember to bring a sweater in case it gets chilly in the cabin.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity. To lessen your risk on board, stay hydrated, consider wearing compression socks and keep your feet and legs moving.
How to get through airport security fast when flying to Union?
As savvy travellers know, the secret is to be prepared before you reach the security gate. That way, you'll be stepping onto that plane to Union in next to no time. Follow these tips and get your holiday off to a great start:
  • Have your travel documents and ID within close reach. They're the first items you'll be asked to present to security.
  • Next up is the X-ray machine. Remove anything on you that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • All electronic gadgets, including your tablet and phone, must also be separately scanned.
  • Can't travel without your favourite perfume or cologne? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can keep it with you in your carry-on luggage.
  • Slip-on shoes are a practical footwear choice as you're less likely to have to remove them when passing through security. Big boots and heavier-style shoes are usually subjected to extra screening.
  • Sharp or pointed objects (like knives and scissors) are prohibited in the cabin. They'll be confiscated at security, so pack them in your checked bags.
