Do you have any tips for my flight to Denver?
We've rounded up all the info you need to make your journey as enjoyable as possible. Follow our top tips and you'll be hightailing it through the airport and enjoying Denver before you know it. What to pack in your hand luggage:
  • A plane trip can be a pleasure if you've got all the right stuff. Firstly, you'll want some basic toiletries, such as toothpaste, a toothbrush and some deodorant, a fresh change of clothes and a magazine or two. Next, find room in your carry-on bag for your electronic devices, chargers, any medications and maybe a comfy neck pillow too. Lastly, don't forget to bring your passport, travel docs and some cash.
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 one of the compartments of your carry-on luggage. Other banned items include explosive or flammable substances, such as aerosol cans and fuel, and liquids and gels in containers larger than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your aim is to be as comfortable as possible. Go for shoes that are easy to slip on and off, dress in loose, natural fibers and don't forget to bring a sweater in case you get cold in the cabin.
  • Deep vein thrombosis (DVT) can pose a risk on long-distance flights. It results from blood clotting due to poor circulation and inactivity, so do some gentle leg and foot exercises in your seat and consider wearing compression socks or tights.
How to get through airport security fast when flying to Denver?
The trick is to be well prepared before you get to security. That way, you'll be boarding that plane to Denver in no time at all. Follow these tips and get your holiday off to a great start:
  • First things first. Your boarding pass and passport will need to be inspected by airport security. Keep them at hand to avoid fumbling around for them.
  • Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like your headphones, will need to go on a tray through the X-ray machine. Make your life easier by removing them as your turn draws near.
  • Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Any liquids or gels, such as hair oil or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several minutes. Boots are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them in your checked luggage. They won't be allowed in the cabin.
