Do you have any tips for my flight to Aspen?
We've pulled together all the info you need to make your flight as pain-free as possible. Follow our tips and you'll be hightailing it through the airport and having a ball in Aspen before you know it. What to pack in your hand luggage:

  • Air travel can be a cruisy experience if you've got all the right gear. First of all you'll need basic toiletry items, such as deodorant and a toothbrush, a spare pair of socks and a good novel. Secondly, make room in your bag for your phone, tablet and chargers, any daily medications and maybe a proper neck pillow as well. Lastly, and most importantly, don't forget to take your passport, travel docs and some cash.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like your trusty pocket knife, and dangerous products which are flammable or explosive, such as flares, bleaching agents and poisons, are also not allowed.

What to wear on a flight:

  • Comfort should be your main concern when choosing what to wear during your flight. Loose, breathable clothing is a wise choice, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Aspen?
It's all about being prepared. We've put together some helpful hints for a speedy trip through airport security. Look out Aspen, here you come:

  • Be sure to keep your boarding pass and passport easily accessible. They'll be the first things you'll be asked to present to airport security.
  • Next up, both you and your hand luggage will be X-rayed. To make the process quick and painless, take off anything that is likely to set the alarm off. Items like your belt, coat and earphones will be required to go through the machine.
  • For just a few minutes, you'll have to unplug from the digital world. Your phone, laptop and any other electronic gadgets also need to be sent through the scanner.
  • Remember to remove gels and liquids from your carry-on luggage. They usually need to be sent through the X-ray machine separately. Each product should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you several minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
  • Airlines won't allow any pocket knives or other sharp items in your carry-on luggage. If you need to bring these kinds of items, pack them in your checked baggage.
