Do you have any tips for my flight to Denver?
Depending on where you're coming from, your flight to Denver could be completely stress-free or it could go on forever. Here are some handy tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

  • A plane trip can be a great experience if you bring the right gear. Firstly, you'll want some basic toiletries, such as deodorant, toothpaste and a toothbrush, a clean pair of socks and a few magazines. Next, find a spot in your carry-on bag for your mobile phone, a charger, any medications and maybe a proper neck pillow as well. Last, but definitely not least, remember to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your Swiss Army knife, and dangerous goods which are explosive or flammable, such as aerosols and matches, are also banned.

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes by dressing in layers, and pick closed-toe, flat shoes like slip-ons.
  • The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-distance flights. Lower your risks by drinking water, keeping your legs moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Denver?
As seasoned travellers know, the secret is to be well prepared before you reach security. That way, you'll be hopping onto that plane to Denver before you know it. Follow these tips and get your trip off to a spectacular start:

  • First things first. Your passport and travel documents will need to be shown to airport security personnel. Have them easily accessible to avoid fumbling around for them.
  • After that, both you and your carry-on luggage must be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items such as your jacket, belt and earphones need to go through the machine.
  • All electronic gadgets, including your phone and tablet, will also need to be scanned separately.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • There's a possibility that you'll be required to take your shoes off to be X-rayed, so wearing slip-on sneakers is always a smart idea.
  • Avoid taking prohibited items in 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.
