Do you have any tips for my flight to Keystone?
Depending on where you're coming from, your journey to Keystone could be completely painless or it could go on forever. We've pulled together some handy hints that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

  • First of all, put in your passport, travel documents, bank cards and medications. Next, you'll want some entertainment to while away the hours. A juicy book and a tablet crammed with your favourite shows are some terrific options. If you plan to take a short nap, a comfy neck pillow and some earplugs will also come in handy. Finally, make room for a toothbrush and some facial wipes so you'll step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Sharp objects, like your precious Swiss Army knife, and dangerous goods which are flammable or explosive, such as flares, chemicals agents and strong acids, are also not allowed.

What to wear on a flight:

  • Comfort should be your top priority when choosing what to wear on your flight. Loose, breathable clothing is a wise option, as are flat, slip-on shoes.
  • Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Make a point of walking around the cabin or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Keystone?
The answer is simple — be prepared. We've rounded up some top tips for a fuss-free trip through airport security. Watch out Keystone, here you come:

  • Be sure to have your passport and boarding pass within easy reach. They're the first things you'll be asked to show at airport security.
  • The X-ray machine comes next. Empty your pockets and remove anything that is likely to beep. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • All electronic gadgets, including your phone and tablet, are also required to be scanned separately.
  • Remember to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a single quart-size (one litre), clear zip-close bag.
  • Lightweight sneakers are a great footwear choice as you're less likely to have to remove them when passing through security. Big boots and other bulky shoes are usually 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.
