Do you have any tips for my flight to Idaho Falls?
If you're not prepared, air travel can be tough. But there's no need to worry. Follow these useful tips and enjoy a comfortable start to your time in Idaho Falls. What to pack in your hand luggage:
  • First and foremost, pack your passport, official ID, credit cards and daily medications. Next, you'll need some extra in-flight entertainment to help pass the time. A thrilling novel and a tablet filled with your favourite movies are some terrific options. If you plan to catch up on some sleep, a comfy neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, leave some space for a toothbrush and some deodorant so you'll touchdown looking and feeling fresh.
Do not pack the following items in your hand luggage:
  • Double-check that you don't have sharp or pointed objects lurking in one of the zippers of your carry-on luggage. Other banned items include explosive or flammable goods, such as aerosol cans and bleach, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Comfort should be your main priority when choosing what to wear on board. Loose clothing is a sensible option, as are flat, enclosed shoes.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of sitting. To lower your risk on board, drink plenty of water, consider wearing compression tights or socks and keep your feet and legs moving.
How to get through airport security fast when flying to Idaho Falls?
Being organized before you arrive at the airport can make your getaway to Idaho Falls a breeze. Below are some handy tips for a swift journey past security:
  • Your boarding pass and passport will need to be inspected by security personnel. Keep them within easy reach to avoid fumbling around for them.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
  • Your electronic devices like phones and laptops will also need to go on a tray to be scanned. Don't worry though, you'll be back online in no time.
  • Any liquids or gels, such as perfume or hairspray, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-close bag.
  • Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other heavy-style shoes are usually subjected to additional screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp or pointed objects, pack them safely away in your checked luggage. They won't be allowed on board.
