Do you have any tips for my flight to Boulder?
Wherever you're jetting in from, flying can be an enjoyable experience if you're prepared. We've made a list of top travel tips that will get your Boulder holiday started on the right note. What to pack in your hand luggage:
  • It's easy — first, pack your passport, important documents, credit cards and vital medications. Next, you'll need some extra in-flight entertainment to while away the time. A juicy novel and a laptop filled with your favourite shows are some great options. If you intend to take a quick snooze, a neck pillow and a pair of earplugs will also come in handy. Finally, squeeze in a toothbrush and some facial wipes so you'll arrive feeling fresh and raring to go.
Do not pack the following items in your hand luggage:
  • While the list of banned items differs between airlines, the general rule of thumb is avoid carrying anything flammable, sharp or explosive. This includes things like knives, scissors, aerosol cans and bleaching agents. Sporting equipment like bows and arrows, and objects that could injure passengers, such as firearms and swords, aren't allowed in the cabin either.
What to wear on a flight:
  • The aisles of a plane aren't the place for a fashion parade. Don comfortable layers and opt for shoes that are flat and easy to remove.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some simple exercises in your seat to promote better circulation.
How to get through airport security fast when flying to Boulder?
A little pre-planning before you arrive at the airport can make your getaway to Boulder a pleasure. Check out our handy tips and tricks for a speedy journey past security:
  • First things first. Your travel ID and boarding pass will need to be presented to airport security personnel. Have them close by so you don't hold up the queue.
  • The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to beep. This includes items like headphones or earphones, as well as heavy jackets or coats. They'll need to be placed on the conveyor belt for screening.
  • Your electronic devices like laptops and phones will also have to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Want to bring along your favourite perfume or cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can keep it with you on board.
  • The right choice of footwear can save you several valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed on board and will be confiscated.
