Do you have any tips for my flight to Keystone?
We've rounded up all the info you need to make your journey an enjoyable experience. Follow our insider tips and you'll be speeding through the airport and having a blast in Keystone in no time at all. What to pack in your hand luggage:

  • It's simple — first, put in your passport, travel documents, cash and vital medications. Next, you'll want some in-flight entertainment to while away the hours. A juicy novel and a phone crammed with your favourite shows are some fantastic options. If you intend to take a quick nap, a neck pillow and a pair of earplugs will also come in handy. Finally, make room for a toothbrush and some cleansing wipes to ensure you arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Squeeze 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. Pointed or sharp objects, like your trusty Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosol cans, spray paint and fuels, are also not allowed.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Wear layers and pick shoes that are flat, enclosed and easy to remove.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It's the result of blood clotting due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.

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

  • Have your ID and travel documents someplace easily accessible. They're the first things you'll be asked to present to airport security.
  • Time to strip down. Well sort of. Your belt, coat, keys and other small items, like your headphones, will be required to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • All your electronic gadgets, including your phone and tablet, are also required to be scanned separately.
  • Travelling with your favourite hand cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you in your carry-on bag.
  • Slip-on shoes are a clever footwear choice as you're less likely to be asked to remove them when passing through security. Boots and other bulky shoes are usually subjected to extra screening.
  • Sharp items are not allowed in the cabin. They'll be seized at security, so pack them safely away in your checked luggage.
