Do you have any tips for my flight to Keystone?
Wherever you're jetting in from, flying can be a pleasurable experience if you prepare well enough. We've compiled a list of handy tips and tricks that will help get your Keystone holiday started on the right foot. What to pack in your hand luggage:

  • Travelling on a plane can be a comfortable experience if you take the right gear. Firstly, you'll want a few basic toiletry items, such as a toothbrush and hairbrush, a fresh set of clothes and a good novel. Next, find room in your bag for your phone, tablet and chargers, any vital medications and perhaps a blow-up neck pillow too. Last, but definitely not least, be sure to take your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes tools, metal cutlery, fuels and bleaching agents. Sporting equipment like ice skates, and items that could harm passengers, such as pepper spray and firearms, won't be allowed on board either.

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes by layering up, and pick flat, slightly roomy shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Walk around the cabin and give your legs a stretch or do some simple exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Keystone?
As savvy travellers know, the secret is to be well organised before you get to the airport security gate. That way, you'll be hopping onto that plane to Keystone before you know it. Follow these helpful tips and get your trip off to a flying start:

  • Security personnel first need to verify that you have a valid passport and matching boarding pass before anything else. Have them ready to show.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that might trigger the alarms. Personal belongings like your coat, belt and earphones will be required to go through the machine.
  • For just a few minutes, you'll need to unplug from technology. Your phone, laptop and any other electronic devices also need to be sent through the scanner.
  • Remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray scanner separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several valuable minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Airlines will not allow any pocket knives or other sharp items in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked baggage.
