If you intend to catch up on some sleep, a comfy neck pillow and some noise-cancelling headphones will also be useful. Finally, leave some space for a toothbrush and some deodorant to ensure you step off the plane feeling fresh and ready to go.
Do not pack the following items in your hand luggage:
  • Check carefully that you don't have a pocket knife hiding in your carry-on luggage. Other prohibited items include explosive or flammable substances, like aerosols and matches, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).
What to wear on a flight:
  • Your top priority is to feel as comfortable as you can. Go for shoes that are easy to pull on and off, dress in loose, natural-fibre clothing and don't forget to bring a jacket in case you get chilly in the cabin.
  • You've probably heard about deep vein thrombosis (DVT), a blood clotting condition caused by prolonged periods of sitting. To lower your risk on board, stay hydrated, consider wearing compression socks and do gentle foot and leg exercises in your seat.
How to get through airport security fast when flying to Cascade Locks?
It's all about being organized. We've pulled together some useful tips for a stress-free trip through security. Watch out Cascade Locks, here you come:
  • Have your passport and boarding pass easily accessible. They're the first things you'll be asked for by airport security.
  • After that, both you and your hand luggage must be X-rayed. To speed things up, take off anything that is likely to set the alarm off. Items like your jacket, belt and headphones need to go through the machine.
  • Your electronic gadgets like laptops and phones will also have to go through the machine to be scanned. Don't worry though, you'll be back online before you know it.
  • Remove all liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Lightweight sneakers are a great footwear choice as you're less likely to have to remove them when going through security. Hiking boots and heavier-style shoes are often subjected to extra screening.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked luggage. They won't be allowed in the cabin.
