Do you have any tips for my flight to Keystone?
Depending on where you're coming from, your trip to Keystone could be completely stress-free or it could drag on forever. We've put together some handy hints that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • First things first, put in your passport, travel docs, bank cards and vital medications. Next, you'll want some entertainment to help pass the time. A juicy book and a phone filled with your favourite shows are some great options. If you intend to take a short snooze, a neck pillow and a pair of noise-cancelling headphones will also be useful. Finally, make room for a toothbrush and some deodorant so you'll hop off the plane looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other restricted items include explosive or flammable goods, such as aerosol cans and bleach, and gels and liquids in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Choose comfort over style. Prepare for temperature changes in the cabin by layering up, and opt for slightly roomy, flat shoes like sneakers.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clots forming due to inactivity and poor circulation, so do some gentle foot and leg exercises in your seat and consider wearing compression socks.

How to get through airport security fast when flying to Keystone?
As savvy travellers know, the secret is to be prepared before you arrive at the airport security gate. That way, you'll be boarding that plane to Keystone in no time flat. Follow these tips and get your trip off to a flying start:

  • Your passport and travel documents will need to be inspected by airport security personnel. Have them easily accessible so you don't hold up the line.
  • The X-ray machine is up next. Remove anything metal on you 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.
  • All your electronic gadgets, including your phone and laptop, must also be scanned separately.
  • Any gels or liquids, such as hair oil or hand cream, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a good footwear choice as you're less likely to be asked to remove them when passing through security. Safety boots and heavier-style shoes are often 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, pack them safely away in your checked baggage. They won't be allowed on board and will be confiscated.
