Do you have any tips for my flight to Denver?
We've pulled together all the info you need to make your flight as enjoyable as possible. Follow our top tips and you'll be hightailing it through the airport and seeing the best of Denver before you know it. What to pack in your hand luggage:

  • It's simple — first, pack your passport, travel documents, wallet and daily medications. Next, you'll want some entertainment to while away the time. A thrilling book and a tablet crammed with your favorite movies are some fantastic options. If you plan to take a quick nap, a neck pillow and a pair of earplugs will also come in handy. Finally, find room for a few toiletry items so you'll arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp or pointed objects hiding in your carry-on luggage. Other banned items include explosive or flammable substances, such as aerosol cans and bleach, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

  • The aisles of an airplane are no place for a fashion parade. Layer your clothing and pick shoes that are roomy, flat and easy to remove.
  • The result of prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long flights. Reduce the risks by drinking water, keeping your legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to Denver?
As seasoned travelers know, the secret is to be prepared before you get to security. That way, you'll be boarding that plane to Denver in next to no time. Follow these tips and get your trip off to a flying start:

  • Have your passport and travel documents handy. They're the first things you'll be asked for by airport security.
  • Next up, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Items such as your belt, jacket and headphones need to go through the machine.
  • For just a few moments, you'll need to unplug from technology. Your phone, laptop and any other electronics will need to be sent through the scanner.
  • Don't forget to remove liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a quart-size (one liter), clear zip-close bag.
  • It's also likely that you'll be asked to remove your shoes for scanning, so wearing slip-on shoes is always a smart idea.
  • Airlines won't allow any sharp objects in your carry-on luggage. If you need to bring these kinds of items, check them in.
