Do you have any tips for my flight to Denver?
Depending on where you're coming from, your trip to Denver could be a breeze or it could drag on forever. Below are some handy hints that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:
  • Firstly, and most importantly, pack your passport, travel documents, cash and vital medications. Next, you'll want some in-flight entertainment to help pass the time. A juicy book and a tablet filled with your favourite movies are some wonderful options. If you plan to catch a few z's, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, find room for a toothbrush and some deodorant to ensure you arrive at your destination looking fresh and ready to go.
Do not pack the following items in your hand luggage:
  • While the list of restricted items can differ between air carriers, the general rule of thumb is nothing sharp, flammable or explosive. This includes knives, scissors, aerosol cans and flares. Sporting equipment like ski poles, and objects that could injure passengers, such as firearms and ammunition, can't come on board with you either.
What to wear on a flight:
  • Comfort should be your highest priority when choosing what to wear on board. Loose, breathable clothing is a smart choice, as are flat, closed-toe shoes.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clots forming 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?
It's all about being prepared. We've pulled together some useful tips for an easy trip through security. Look out Denver, here you come:
  • First things first. Your travel documents and ID will need to be presented to security personnel. Keep them someplace accessible so you don't hold up the queue.
  • After that, both you and your carry-on bag will be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Personal belongings like your belt, coat and headphones need to go through the machine.
  • Your electronic gadgets like laptops and phones will also need to go on a tray for inspection. Don't worry, you'll be back online soon enough.
  • Remove liquids and gels from your carry-on bag. They usually need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several minutes. Boots and heavy shoes are often required to be removed and X-rayed separately. Lightweight sneakers are usually not.
  • Sharp items such as knives and scissors can't be taken on board. They'll be seized at security, so pack them in your checked bags.
