Do you have any tips for my flight to Black Diamond?
We've got the lowdown on how to make your flight a stress-free experience. Follow our top tips and you'll be speeding through the airport and having a ball in Black Diamond in no time at all. What to pack in your hand luggage:
  • First and foremost, pack your passport, travel docs, bank cards and medications. Next, you'll need some in-flight entertainment to while away the time. A thrilling book and a tablet crammed with your favourite shows are some terrific options. If you intend to catch a few z's, a quality neck pillow and some noise-cancelling headphones will also come in handy. Finally, find room for a few toiletry items to ensure you hop off the plane looking fresh and ready to go.
Do not pack the following items in your hand luggage:
  • While the list of prohibited items differs between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes screwdrivers, knives, fuels and bleaching agents. Sports equipment like ice skates, and items that could harm other people, such as swords and batons, can't come on board with you either.
What to wear on a flight:
  • Comfort should be your highest priority when deciding what to wear during your flight. Loose, breathable clothing is a smart option, as are roomy, closed-toe shoes.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To minimize your risk on board, drink lots of water, consider wearing compression socks and move your legs and feet often.
How to get through airport security fast when flying to Black Diamond?
A little pre-planning before you arrive at the airport will help make your getaway to Black Diamond quick and painless. Read through our top tips for a swift journey past security:
  • Have your travel documents and passport easily accessible. They're the first items you'll be asked for by security.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as heavy coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few minutes, you'll have to unplug from technology. Your phone, tablet and any other electronics must also go through the scanner.
  • Any liquids or gels, such as shampoo or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be confiscated at security, so put them in your checked bags.
