Do you have any tips for my flight to Treasure Valley?
Wherever you're jetting in from, flying can be an enjoyable experience if you've prepared well enough. Follow these handy tips that will get your Treasure Valley escape started on the right note. What to pack in your hand luggage:

  • Firstly, and most importantly, pack your passport, official ID, credit cards and medications. Next, you'll need some entertainment to while away the time. A thrilling novel and a laptop crammed with your favourite shows are some wonderful options. If you plan to take a quick snooze, a quality neck pillow and some earplugs will also be useful. Finally, make room for a toothbrush and some deodorant to ensure you arrive at your destination feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items differs between air carriers, the general guide to follow is avoid carrying anything sharp, flammable or explosive. This includes things like box cutters, razor blades, spray paint and flares. Sports equipment like golf clubs, and items that could injure passengers, such as firearms and swords, are also banned from the cabin.

What to wear on a flight:

  • Your goal here is to feel as comfortable as you can. Pick shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and don't forget to take a jacket in case you get chilly in the cabin.
  • Caused by sustained periods of immobility, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers during long flights. Reduce the risks by staying hydrated, keeping your legs and ankles moving and wearing compression socks or tights.

How to get through airport security fast when flying to Treasure Valley?
As savvy travellers know, the secret is to be organized before you reach the security gate. That way, you'll be stepping onto that plane to Treasure Valley before you know it. Follow these helpful tips and get your vacation off to a great start:

  • Your passport and boarding pass will need to be presented to airport security. Have them close by to avoid fumbling around for them.
  • The X-ray machine comes next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • All your electronic gadgets, including your tablet and phone, are also required to be scanned separately.
  • Any liquids or gels, such as perfume or hairspray, that you want to take 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), clear zip-lock bag.
  • It's also likely that you'll need to take your shoes off to be X-rayed, so wearing lightweight sneakers is always a good idea.
  • Airlines will not allow any sharp items or pocket knives to come on board with you. If you must bring these kinds of items, put them in your checked baggage.
