Do you have any tips for my flight to Fort Collins?
If you're not prepared, air travel can be testing. But there's no need to hit the panic button just yet. Follow these useful tips for a worry-free start to your time in Fort Collins. What to pack in your hand luggage:
  • The trick to having a hassle-free flight experience is to be prepared. So, let's start with the basics: passport, official ID, cash and any vital medications. Next, bring on board items that'll help keep you busy, like some electronic gadgets or a juicy novel. It's also a wise idea to pack your chargers, a comfy neck pillow and a pair of headphones. Last but not least, don't forget to toss in toiletries like a toothbrush, cleansing wipes and a spare set of clothes.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have a Swiss Army knife hiding in one of the zippers of your hand luggage. Other banned items include explosive or flammable goods, such as aerosol cans and bleach, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your top priority is to be as comfortable as possible. Choose slip-on footwear, dress in loose, natural-fibre clothing and remember to bring a jacket in case it gets chilly in the cabin.
  • You've probably heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To minimize your risk on board, stay hydrated, consider wearing compression socks and move your legs and feet often.
How to get through airport security fast when flying to Fort Collins?
The answer is simple — be prepared. We've pulled together some top tips for a stress-free trip through security. Look out Fort Collins, here you come:
  • Have your ID and travel documents someplace easily accessible. They're the first items you'll be asked to present to airport security.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • All your electronics, including your phone and laptop, are also required to be scanned separately.
  • Can't travel without your favourite hand and nail cream? Not a problem. As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, you're allowed to bring it with you on board.
  • It's also possible you'll need to take your shoes off for scanning, so wearing slip-on sneakers is always a clever idea.
  • Airlines won't allow any sharp objects in your hand luggage. If you must bring these kinds of items, pack them safely in your checked luggage.
