Do you have any tips for my flight to Grey Summit?
No matter where you're coming from, flying can be an enjoyable experience if you've prepared well. We've compiled a list of handy tips that will help get your Grey Summit vacation started on the right foot. What to pack in your hand luggage:

  • First, pack your passport, travel docs, credit cards and medications. Next, you'll need some extra in-flight entertainment to help pass the time. A thrilling novel and a tablet crammed with your favourite shows are some fantastic options. If you intend to catch a few z's, a neck pillow and some earplugs will also come in handy. Finally, make room for a toothbrush and some deodorant to ensure you step off the plane looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your treasured pocket knife, and products which are flammable or explosive, such as aerosols and fireworks, are also not allowed.

What to wear on a flight:

  • Comfort should be your highest priority when deciding what to wear on board. Loose clothing is a sensible option, as are flat, slip-on shoes.
  • Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To minimize your risk on board, stay hydrated, consider wearing compression tights or socks and move your lower limbs often.

How to get through airport security fast when flying to Grey Summit?
Being prepared before your flight will make your trip to Grey Summit a breeze. Here are some top tips for a speedy journey through security:

  • Have your travel documents and ID close by. They're the first things you'll be asked to present to airport security.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the alarm. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • For just a few moments, you'll need to unplug from technology. Your laptop, phone and any other electronic gadgets will need to go through the scanner.
  • Remove liquids and gels from your carry-on luggage. They usually need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • It's also likely that you'll be required to remove your shoes for scanning, so wearing slip-on sneakers is always a wise idea.
  • Knives and other sharp items are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked suitcase.
