Do you have any tips for my flight to Great Falls?
Depending on where you're coming from, your flight to Great Falls could be as easy as pie or it could drag on forever. Here are some handy hints that will help you start your next unforgettable escape on the right foot. What to pack in your hand luggage:

  • It's simple --- first, put in your passport, important documents, bank cards and daily medications. Next, you'll want some extra in-flight entertainment to while away the time. A thrilling book and a laptop filled with your favourite shows are good options. If you plan to catch forty winks, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, leave space for a few toiletry items to ensure you arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like your trusty Swiss Army knife, and products which are flammable or explosive, such as spray paint, flares and strong acids, are also prohibited.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Don comfortable layers and go for shoes that are enclosed, flat and easy to slip on and off.
  • The result of sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-distance flights. Lower your risks by drinking water, keeping your ankles and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Great Falls?
As seasoned travellers know, the secret is to be prepared before you reach the security gate. That way, you'll be stepping onto that plane to Great Falls in the blink of an eye. Follow these helpful tips and get your vacation off to a great start:

  • Keep your ID and boarding pass easily accessible. They're the first things you'll be asked for by security.
  • After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Personal belongings like your belt, coat and earphones will be required to go through the machine.
  • Electronic devices like phones and laptops will also have to go on a tray to be scanned. No need to worry though, you'll be back online in no time.
  • Travelling with a new cologne or perfume? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on.
  • Slip-on shoes are a clever footwear choice as you're less likely to be required to remove them when going through security. Hiking boots and other bulky shoes are usually subjected to extra screening.
  • Sharp items such as knives and scissors are prohibited in the cabin. They'll be seized at security, so put them in your checked bags.
