  • First things first, pack in your passport, important documents, bank cards and medications. Next, you'll want some extra in-flight entertainment to while away the hours. A juicy book and a laptop filled with your favourite movies are some fantastic options. If you plan to take a quick snooze, a neck pillow and a pair of earplugs will also be useful. Finally, make room for a toothbrush and some facial wipes so you'll touchdown looking fresh and ready to go.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a Swiss Army knife hiding in one of the zippers of your carry-on luggage. Other prohibited items include flammable or explosive goods, such as aerosol cans and fuel, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in cabin temperature by wearing layers, and wear closed-toe, flat footwear like sneakers.
  • Deep vein thrombosis (DVT) is a potential risk on long-haul flights. It's the result of blood clotting due to poor circulation, 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 Longmont?
The simple answer is — be prepared. We've put together some helpful hints for a hassle-free trip through airport security. Watch out Longmont, here you come:

  • Be sure to keep your passport and travel documents handy. They're the first items you'll be asked for by security.
  • After that, both you and your carry-on bag will be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Items like your belt, coat and headphones need to go through the machine.
  • All electronic devices, including your phone and tablet, are also required to be separately scanned.
  • Any gels or liquids, such as perfume or toothpaste, that you want to bring on board need to be in containers no larger than 3.4 ounces (100 millilitres). They must also all fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several valuable minutes. Boots and heavy shoes are often required to be removed and separately scanned. Lightweight sneakers are usually not.
  • Sharp or pointed objects (like knives and scissors) are not allowed in the cabin. They'll be seized at security, so pack them in your checked baggage.
