How to survive the flight to Denver?
We’ve got the lowdown on how to make your journey a pleasant experience. Follow our tips and you’ll be breezing through airport security and seeing the best of Denver before you know it.What to pack in your hand luggage:

  • The secret to having an awesome travel experience is to pack ahead. So, let’s start with the basics: passport, official ID, credit cards and medications. Next, bring items that’ll help pass the time, like some electronic devices or a few magazines. You’ll also want to bring your chargers, a comfy neck pillow and a pair of earplugs. And of course, be sure to pop in toiletries like a toothbrush, facial wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don’t have sharp objects (like a knife or scissors) lurking in the bottom of your carry-on luggage. Other banned items include explosive or flammable goods, such as fuel and fireworks, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The best way to ensure a comfortable flight is as simple as your choice of clothes. Prepare for temperature changes by bringing layers. This will keep you nice and warm if the cabin starts to cool down. Shoes like sandals and heels are best left for other occasions. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will thank you later.
  • You’ve probably heard about DVT (deep vein thrombosis), a blood clot condition caused by long periods of sitting. There are numerous ways to lessen your risk. Wear a good-quality pair of compression tights or socks, drink plenty of water and keep your legs and feet moving. Walk around the cabin when possible or try out some simple stretches in your seat.

How to get through airport security fast when flying to Denver?
The trick is to be prepared before you get to security. That way, you’ll be hopping onto that plane to Denver in a flash. Follow these tips and get your trip off to a fantastic start:

  • Be sure to keep your passport and travel documents handy. They’re the first items you’ll be asked for by airport security.
  • Next up, both you and your carry-on bag will be X-rayed. To make the process quick and painless, take off anything that is likely to trigger the alarm. Personal belongings such as your belt, coat and headphones will be required to go through the machine.
  • Your electronic gadgets like phones and laptops will also need to go on a tray for inspection. Don’t worry though, you’ll be back online in no time.
  • Any gels or liquids, such as perfume or hand cream, that you want to bring on board must be no larger than 3.4 ounces (100 milliliters). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you several valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Lightweight sneakers usually aren’t.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won’t be allowed in the cabin.
