Do you have any tips for my flight to Treasure Valley?
If you're poorly prepared, travelling can be daunting. But there's no need to hit the panic button just yet. Follow these handy hints and enjoy a hassle-free start to your time in Treasure Valley. What to pack in your hand luggage:

  • Air travel can be a stress-free experience if you've got all the right things. Firstly, you'll want a few basic toiletry items, such as lip balm and hand cream, a spare pair of socks and a good novel. Secondly, find a spot in your bag for your laptop, a charger, any vital medications and perhaps a quality neck pillow too. Lastly, and most importantly, remember to take your passport, travel documents and your bank cards.

Do not pack the following items in your hand luggage:

  • Make sure you don't have a pocket knife hiding in your carry-on luggage. Other restricted items include flammable or explosive goods, such as aerosol cans and bleach, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your priority is to be as comfortable as possible. Pick shoes that are easy to slip on and off, dress in loose, breathable clothing and don't forget to bring a sweater in case it gets cold in the cabin.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers during long-distance flights. Lower your risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks to help your circulation.

How to get through airport security fast when flying to Treasure Valley?
Being prepared before your flight will help make your trip to Treasure Valley a piece of cake. Check out our handy hints for a speedy journey through security:

  • Keep your passport and boarding pass within easy reach. They'll be the first things you'll be asked to present to security.
  • After that, both you and your carry-on luggage must be X-rayed. To make the process quick and painless, take off anything that might set the alarms off. Items like your coat, belt and headphones need to go through the machine.
  • Your electronic devices like laptops and phones will also have to go on a tray to be scanned. No need to worry though, you'll be back online soon enough.
  • Any liquids or gels, such as hair oil or hand cream, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
  • It's also likely that you'll be required to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a wise idea.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you need to bring these kinds of items, pack them safely in your checked baggage.
