How to survive the flight to Boulder?
Wherever you’re coming from, flying can be a seamless experience if you’ve planned ahead. Follow these handy hints that will help get your Boulder escape started on the right note.What to pack in your hand luggage:

  • A plane ride can be a pleasure if you carry the right gear. First of all you’ll need basic toiletries, such as a toothbrush and some deodorant, a spare pair of socks and a magazine or two. Next, leave space in your carry-on bag for your laptop, a charger, your important medications and perhaps a comfy neck pillow too. Last, but definitely not least, don’t forget to take your passport, travel docs and some money.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated. Sharp or pointed objects, like your treasured Swiss Army knife, and products which are flammable or explosive, such as flares, chemicals agents and matches, are also restricted.

What to wear on a flight:

  • The answer to a comfortable flight is as simple as your choice of clothes. Prepare yourself for varying temperatures by layering up. That way you’ll stay nice and warm if the cabin gets chilly. Shoes like high heels and sandals are best left in your checked suitcase. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will thank you later.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clotting condition caused by reduced mobility or inactivity. There are numerous ways to minimize your risk. Wear a quality pair of compression tights or socks, drink lots of water often and get your legs and feet moving. Do a lap or two of the cabin or try out some simple stretches in your seat.

How to get through airport security fast when flying to Boulder?
A little pre-planning before your flight can make your getaway to Boulder a piece of cake. Read through our handy tips for a speedy journey past security:

  • First things first. Your travel documents and passport will need to be inspected by airport security personnel. Keep them at hand so you don’t have to dig around for them.
  • The X-ray machine comes next. Remove anything on you that is likely to set off the scanner’s 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.
  • Electronic devices like phones and laptops will also have to go on a tray to be scanned. Don’t worry though, you’ll be back online in no time.
  • Want to bring along your favourite cologne or perfume? No problem. As long as it’s in a container no larger than 3.4 ounces (100 milliliters) and it’s stored in a zip-lock bag, it’s fine to bring with you in your carry-on luggage.
  • There’s a chance you’ll be required to take your shoes off for scanning, so wearing slip-on sneakers is always a wise idea.
  • Airlines will not allow any sharp objects to come on board with you. If you must bring these kinds of items, pack them safely in your checked baggage.
