Do you have any tips for my flight to Boise?
We've rounded up all the info you need to make your journey as stress-free as possible. Follow our tips and tricks and you'll be speeding through the airport and discovering Boise in no time. What to pack in your hand luggage:

  • The secret to having a great travel experience is to pack in advance. So, let's start with the basics: passport, official ID, bank cards and vital medications. Next, bring on board items that'll help pass the time, like your laptop or a thrilling book. It's also smart to bring your chargers, a quality neck pillow and a pair of headphones. Finally, be sure to chuck in toiletries like a toothbrush, deodorant and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have a pocket knife hiding in one of the compartments of your carry-on luggage. Other prohibited items include explosive or flammable substances, such as fuel and fireworks, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in temperature by dressing in layers, and opt for easy-to-remove footwear like sneakers.
  • Deep vein thrombosis (DVT) can pose a risk on long-haul flights. It's the result of blood clots forming due to poor circulation and inactivity, so do some gentle foot and leg exercises in your seat and consider wearing compression tights or socks.

How to get through airport security fast when flying to Boise?
The answer is simple — be organized. We've rounded up some top tips for a speedy trip through airport security. Look out Boise, here you come:

  • Keep your travel documents and ID handy. They're the first items you'll be asked for by security.
  • After that, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that might trigger the alarms. Personal belongings such as your belt, jacket and earphones 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 lip balm or cologne, that you want to take on board need to be in containers no larger than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Hiking boots are often required to be removed and separately scanned. Lightweight sneakers usually aren't.
  • Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked luggage. They won't be allowed in the cabin.
